HR development is one of the principles of SHRM that should be implemented consistently along with other SHRM principles, which means, e.g., that the development of employees should be carried out having a long-term perspective in mind. It is crucial to acquire the so-called competencies of the future as the basis for implementing the idea of Industry 4.0. The purpose of the article is to present the development of human potential in an organization against the background of other detailed sustainable HRM principles, to be followed by confronting the theory and the research results on the development of future competencies referring to industrial engineers in Poland as the professional group responsible for implementing the idea of cleaner production and Industry 4.0. The Author analyzed the results of three research projects based on the survey method and representative data from Eurostat and Statistics Poland. The conducted research shows that industrial companies in Poland have more of a short-sighted perspective when it comes to developing the potential of their engineers. The HR development practices focusing only on current needs are not in line with the SHRM principles of a long-term perspective and flexibility. There is also a visible lack of employee participation in the process of making training-related decisions, which is another principle of sustainable HRM. In addition, environmental sustainability remains a neglected area of knowledge in terms of training, and the cooperation with external educational institutions is low. It results in certain implications for HR managers and educational institutions. The article also presents directions for further research. out having a long-term perspective in mind.

Since the 1980s, a heated debate has been raging over the "proper" approach to managing people in organizations. There is much research that proves there is a strong, positive relationship between human resource management (HRM) practices and a company's performance, including such specific areas as introducing strategy and innovation (Becker and Gerhart, 1996 , Gupta, 2011 , Jiang et al., 2012 , Barba Aragón et al., 2014 , Tian et al., 2018 . HRM function -defined as the activities undertaken by the HR department, such as recruitment and selection, HR appraisal, HR development, and HR rewarding -has evolved from a purely administrative role to a strategic one. In the modern world, continuous organizational changes are becoming the norm. They consist of the reorganization of processes, the optimization of the size of an organization, decentralization, and the blurring of organizational boundaries (Piwowar-Sulej and Bąk-Grabowska, 2018). As Kaur et al. stated , "the long-term success of firms can only be ensured if they adapt their strategic and structural orientation as per the changing environmental and technological scenario" (Kaur et al., 2019, p. 44) . Two emergent theoretical and practical fields related to the environment and technology are sustainability and Industry 4.0, respectively. The results of literature studies conducted by Sharma et al. (2020) indicate that the interest in matching these two above-mentioned body of knowledge has been growing. Sustainable development is generally defined as "meeting the needs of the present generation without compromising the ability of future generations to meet their own needs" (WCED -World Commission on Environment and Development, 1987, p. 49) . This concept is based on three pillars, called the Triple Bottom Line. The first pillar covers environmental development, the second one economic development, and the third pillar is social development (Amos O. and Uniamikogbo, 2016) . It was established in the 1960s as a response to the rapidly growing population and related risks, such as excessive use of natural J o u r n a l P r e -p r o o f resources, environmental pollution, a high unemployment rate, malnutrition, or the destruction of the Earth's surface, especially of forests. The increased discussion on the global environmental problem was initiated by the report "The Limits to Growth" -published by the Club of Rome, founded in 1968 (Meadows et al., 1972 ) -which presented a pessimistic vision of the Earth's fate. Later, the need for sustainable development was highlighted in the Brundtland Commission's report in 1987 (Brundtland, 1987) . Now it has been accepted that sustainable economic growth depends on an adequate degree of sustainable development in terms of social and environmental performance and also on constant learning (Wilson, 2015) . Sustainable human resource management (SHRM) refers to the concept which combines the idea of sustainability with the soft approach to human resources. This approach promotes basing an HRM strategy on fostering a culture of trust and cooperation and on developing employee involvement, one component of which is loyalty to one's employer. The soft approach to HRM aims to achieve adequate financial results, but through the policy of building a good "employer-employee relationship." A soft strategy -according to the research -is effective in retaining an employee for a longer period of time in an organization and encouraging them to share knowledge, work more productive, act with passion and commitment, generate creative ideas in order to achieve the business goals (Smaliukienė et al., 2017 , Ogbeibu et al., 2018 , Kim and Shin, 2019 , Meier et al., 2019 . Recently, significantly more interest in this concept has been observed, but the literature discussing this issue is fragmentary and highly diverse. In addition, one universally applicable, precise definition of this term has not yet been formulated, though the most frequently cited one holds that "sustainable HRM is the pattern of planned or emerging human resource strategies and practices intended to enable organizational goal achievement while simultaneously reproducing the HR base over a long-lasting calendar time and controlling for self-induced J o u r n a l P r e -p r o o f side and feedback effects of HR systems on the HR base and thus on the company itself" (Ehnert, 2009, p. 74) . It is worth mentioning that in the literature on the subject, in addition to sustainable HRM, such concepts as green HRM, socially-responsible HRM, and common good HRM are also present. Green HRM focuses on the role of HRM in attaining environmental performance (Wagner, 2013 . Socially-responsible HRM and common good HRM represent employee-oriented HRM. These concepts are reflected in decent working conditions and employee participation, for example (Dyllick and Muff, 2016, López-Fernández et al., 2018) . Moreover, there are numerous studies indicating a strong, positive correlation between the relevant SHRM practices and company performance -mainly in terms of the environment (Renwick et al., 2013 , Haddock-Millar et al., 2016 , O'Donohue and Torugsa, 2016 , Dumont et al., 2017 , Ogbeibu et al., 2020 . Against this background it is worth mentioning that research conducted by Shen et al. (2018) proved that green HRM practices have a positive influence on non-green workplace outcomes such as, e.g., intention to quit. The principles of SHRM explain how sustainable development can be used with reference to human resource management (HR function). These rules describe the type of HRM which deserves the attribute of "sustainable." An overview of the literature on the subject leads to the conclusion that there are many approaches to the principles of sustainable HRM. Different authors pay attention to various aspects which are important to them (Zaugg et al., 2001 , Cohen et al., 2010 , Ehnert et al., 2016 . On the basis of literature studies, these principles can be divided into general (i.e., having developed along with the concept itself) and detailed (related to specific actions towards employees). The general principles, within the framework of the SHRM concept, include the following (Ehnert et al., 2016): J o u r n a l P r e -p r o o f 1) an awareness of the complex correlations between the human resource management system and the external and internal organizational environment, 2) actions that enable long-term reproduction of the resources, and 3) recognition and reconciliation of multiple -potentially contradictory -economic, ecological, and social goals. Among the numerous detailed principles of sustainable HRM, the development of human resources is mentioned. As indicated before, HR development is simultaneously one of the basic elements of HR function. Gladwin et al. (1995) directly indicated that sustainability means the development of human potential. A far-sighted perspective requires the competencies of the future to be taken into account in the course of development processes. These competencies guarantee employment both today and in the future and are associated with the changes occurring in the modern world. This particularly refers to the development of the Fourth Industrial Revolution (including the idea of Industry 4.0), following which people and machines are mutually connected in order to simplify all processes which are being digitized. Industry 4.0 has four main characteristics: horizontal integration across countries and continents, vertical networking aiming at individualized production (Whysall et al., 2019) , through-engineering, and acceleration through exponential technologies (Deloitte, 2015) . As Whysall, Owtram, and Brittain state, "the speed of technological change brought about by Industry 4.0 had created a significant gap between the current capability of employees and the rapidly evolving requirements of their roles, prompting a need to consider new and more effective approaches to human resources development" (Whysall et al., 2019, p. 118) . Industrial engineers are the core group of employees in the context of these changes. They "design, develop, test, and evaluate integrated systems for managing industrial production processes, including human work factors, quality control, inventory control, J o u r n a l P r e -p r o o f logistics and material flow, cost analysis, and production coordination" (Frey and Osborne, 2020) . In 1982, they were called the architects of the future (Forman, 1982) . It is justified to continue referring to them in this way, since they introduce product and process innovations that are not only crucial for the survival and growth of organizations (Tohidi and Jabbari, 2012) but that also result in high-quality goods supplied to society and generate economic growth (Ahlstrom, 2010) . As far as sustainability is concerned, engineers are responsible for the implementation of innovations aiming at cleaner production, which is defined as "a preventive environmental management strategy, which promotes eliminating waste before it is created to systematically reduce overall pollution generation, and improve efficiencies of resource use" (UNEP -United Nations Environment Programme, 2014, p. 3) . It is worth mentioning that the cleaner production can be one of the many effects of implementing the Industry 4.0 concept. Digitizing manufacturing means an increase in manufacturing productivity, but this also has an impact on the economic bottom line. It may optimize the trade-off between energy consumption and machine processing cost (Rajput and Singh, 2020) , influence resource efficiency through waste reduction and can minimize carbon emission (environmental bottom line) (Oláh et al., 2020) . Moreover, the Internet of Things -as one of the elements of Industry 4.0 -can bring about new environmentally-friendly products (social, economic, and environmental bottom line) (Kamble et al., 2018 , Braccini and Margherita, 2018 , Ghobakhloo, 2020 . In this way, engineers contribute to the development of a sustainable circular economy (de Oliveira Neto et al., 2020) . The lack of specific knowledge on "what to do and when to do it" is one of the crucial barriers in moving manufacturing industry towards Industry 4.0 (Müller et al., 2018) and sustainability (Koho et al., 2015 , Garcés-Ayerbe et al., 2019 . As Chiappetta Jabbour et al. (2019) state, while the technical side of the circular economy has been broadly discussed, its "human side" requires further investigation. Sharma J o u r n a l P r e -p r o o f et al. (2020), likewise, state that "the link between the social dimension of sustainability and the use of digital technologies should be developed further". This is an important justification for addressing the problem of developing production engineers' competencies. The purpose of the article -its theoretical section -is to present how the development of human potential in an organization should be organized against the background of other detailed principles of SHRM. In other words, the paper answers the basic academic questions of "what and how to do" (Whetten, 1989) The article contributes to theory development in a few ways. Firstly, the author provides a description of one of the principles of SHRM (and one of the elements of HR function, namely, HR development) including a set of relationships between this principle and other HRM principles. Secondly, the idea of sustainable HRM -with a focus on HR development -is combined with the concept of Industry 4.0. The developed theory offers "a statement of relations between concepts within a set of boundary assumptions and constraints" (Bacharach, 1989, p. 496) . Thirdly, the link between the above-mentioned conceptual framework and the empirical research is presented. Finally, the author formulates directions for further research with the focus on sustainability. Human resources development -as an element of HR function -in the general literature on HRM is defined as the "integrated use of training and development, career paths, and organizational development to improve individual and organizational effectiveness" (McLagan and Suhadolnik, 1989, p. 1) . Sims (2006) links the development of personnel to such concepts as learning, performance, and changes. The main instrument of human resources development is appropriate training. Training means a "systematic development of the knowledge, skills, and expertise required by a person to effectively perform a given task or job" (Schmidt, 2007, p. 483) . The basic assumption in general HRM is that employers should focus on the competencies required to achieve their business objectives and should remain competitive and agile, which requires them to ensure their employees receive the J o u r n a l P r e -p r o o f necessary training to fill these competency gaps. Employees need to acquire competencies "on demand" in order to adapt to their changing roles and responsibilities (Hinton, 2018) . Some authors discussing the issue of sustainable HRM focus on HR function (called also HR bundles) and include HR training within this function (Jackson et al., 2011 , Ogbeibu et al., 2020 . Others discuss the "dimensions" of SHRM which go beyond HR function and include, e.g., teamwork, organizational culture, or top management support (Jabbour and Santos, 2008 , Dumont et al., 2017 , Piwowar-Sulej, 2020a , Muduli et al., 2020 . Still others address the conditions connected with HRM, which must be fulfilled in order to build a sustainability-driven organization. They include organizational justice, psychological empowerment, green balance between professional and private life, organizational citizenship behavior, and job satisfaction (Muster and Schrader, 2011, Singh and . Finally, Zoogah (2011) proposes a meta-theory and presents green HRM as a function of a cognitive/social HR information processing system. For the purpose of this article, the conceptual framework presented by Stankevičiūtė and Savanevičienė (2019) was used. Based on literature studies, these authors have prepared -in addition to human resource development -the following list of detailed principles of SHRM: 1) a long-term perspective, 2) flexibility, 3) employee participation or empowerment (involving employees in many decision-making processes beyond those for which their participation is a legal requirement), 4) fair and equal opportunities, 5) the protection of human resources (care of employees), 6) cooperation between employees, 7) the protection of the environment, 8) external partnership, and 9) profitability. The development of human resources is discussed below in relation to the remaining principles of SHRM. The effective implementation of this concept requires all of the rules to be applied simultaneously and the correlations between them to be determined. As highlighted in the Introduction, the development of human resources, taking into account the long-term perspective (Principle 1), means that developing the competencies which employees need "here and now" is insufficient. It is important to define and develop such employee skills which can prove useful for them and the organization in the future. Contemporary organizations must remain flexible. Flexibility (Principle 2) can apply to the entire organization, but also to its individual components, e.g., people. The scientific literature mentions a subjective (referred to as the actor's) approach to flexibility, which states that the flexibility of an organization is determined by the individual flexibility of its participants (Volberda, 1998) . Within the framework of personal flexibility, the following can be listed (Piwowar-Sulej, 2016): • task flexibility, meaning substantive preparation and readiness to undertake tasks specific to other than one's own position From the perspective of SHRM, flexibility is not identified with staff quantitative flexibility. It is not about making ad hoc decisions that involve hiring or dismissing employees. Flexible SHRM is reflected in the ways of organizing work. It covers, e.g., employee rotation and replacement, the possibility of working from home, and a flexible work schedule, which allows it to be tailored to the interests of both the employer and the employee. Referring the indicated attributes of flexible HRM to the problem of human resources development, it should be stated that the first two actions mentioned above (job rotation and substitutions) are considered the training methods (Rekalde et al., 2017) . At this point, it is worth mentioning that it was proven in the 19th century that 90% of the knowledge acquired in a classroom is forgotten after 30 days and 60% after just one hour. Although we live in the 21st century, the research since that time shows that only 10%-20% of the skills learned during training courses are transferred to the workplace (Holton III et al., 2000; Parsloe and Wray, 2008) . The forms of training and methods of work with the training participants are, beyond any doubt, manifested in more extensive specific knowledge, skills, or attitudes. They should be selected according to the purpose and subject of the training and should also respond to the expectations of employees. Listening to employees' suggestions, and taking them into account in the employer's decisions, is part of the process of employee participation (Principle 3). The highest form of employee participation is employee empowerment (Cierniak-Emerych and Piwowar-Sulej, 2017). A flexible training process allows employees to acquire knowledge and skills even from home at a convenient time. This can be achieved by introducing e-learning, which is a subject of the digital development within Industry 4.0. Thus, the training process is carried out with the employees' work-life balance in mind (Stankevičiute and Savanevičiene, 2018) . Treating an employee as the most crucial resource in an organization constitutes the basis for developing a good employee-employer relationship. This means recognizing investment in an employee as the best of all possible options (Becker, 2011) . Furthermore, employees should have fair and equal access (Principle 4) to the training initiatives offered by their employer. It has been proven that organizational justice in fact has a strong impact on job satisfaction, and that a satisfied employee is a predictor of success in the implementation of different organizational activities, including sustainable development . The issue of employees' equality is broadly discussed in the literature on sociallyresponsible HRM Zhu, 2011, Newman et al., 2016) . Care for an employee (protection of employees, or Principle 5) means employee retention and regeneration, among other things (Ehnert, 2009) . As a result of training, employees can acquire various professional (technical) and interpersonal skills. Training can also teach one how to take care of oneself, how to combat stress, and how to develop proper eating or exercise habits in order to regenerate after work. Learning new skills and improving existing competencies brings benefits not only to an employer, but also to the employees themselves. A competent and healthy employee becomes a key employee in an enterprise and has a chance for long-term employment in their Highly developed competencies are gaining importance in times of change, including economic crises. Even if an employee is made redundant, owing to his/her skills, he/she will easily find another job. The development of human resources is closely related to an increase in employability (Blanco, 2014) . Therefore, an employer who is unable to guarantee long-J o u r n a l P r e -p r o o f term employment performs a social mission by facilitating employees in making their way on a competitive job market. At this point, it is worth mentioning that some managers voice concerns that employees trained at the expense of their employer will leave for the competition. This is one of the myths about training courses (McGrath, 2015) . Independent research shows that training is an important factor in employee retention (Khan, 2018; Beynon et al., 2015) . Thus, the competencies of the future should be developed in the form of employee training, all the more so because -due to the current demographic changes -employees are remaining on the job market despite reaching the age of retirement (Fox and O'Connor, 2015) . Sustainable HR development should also increase employees' environmental awareness (Principle 7) taking into account recent developments in rapidly growing body of environmental knowledge (Yang et al., 2021) . In the literature on the subject, HR development in the form of training is considered the basis for building a pro-environmental attitude and a green organizational culture (Susan E. . As the research conducted by has shown, HR training is in the first place on the list of practices considered to be the most effective in shaping employees' pro-environmental behavior. As Cabral and Lochan Dhar (2019) confirmed in their study, green training has a positive impact on enhancing green knowledge and skills. HR training has a positive influence not only on individual performance, but also on employees' collective organizational citizenship behavior towards the environment (Pinzone et al., 2016) and team creativity (Ogbeibu et al., 2020) . Training can be used as a way of responding to barriers to the adoption of environmental practices (Lopes de Sousa . At this place it is worth mentioning that constant changes in technology (called technological turbulence) don't strengthen the positive relationship between green training and team creativity related to solving environmental problems (Ogbeibu et al., 2020) . Taking into account profitability (Principle 9), it should be stated that this principle of SHRM -like the others -is in line with the concept of the Triple Bottom Line. It reflects the economic bottom line. Financial outcomes are no longer the only criteria to measure a company's success, but this area still is important. Profitability in the context of HR development means that competent and motivated employees will contribute to company development and introduce innovations, thus bringing profits to the organization. As indicated above, sustainable HRM practices -including HR development -has a positive influence on a company's performance, including financial indicators (Renwick et al., 2013, O'Donohue and Torugsa, 2016) . In the decision-making process related to training (its forms, the employment of trainers, or the use of modern e-learning technologies), one should take into account the costs as well as the long-term profits . However, it is necessary to consider training first of all as an investment, not an expense. Finally, companies can take advantage of public funds, e.g. from the European Union, devoted to the support of HR development and green-related issues (Guerci and Carollo, 2016) . J o u r n a l P r e -p r o o f According to Deloitte's Industry 4.0 research, enterprises are already subject to digital transformation because of the most frequently mentioned benefits: increased productivity, reduced operational risk, and meeting customer demands to a greater extent (Hanley et al., 2018) . As was pointed out in the Introduction, the Fourth Industrial Revolution combines people and technology. Three alternative scenarios of the technological impact on the future workforce are being discussed (McGowan, 2018) . According to the first of them, work would be optimized through automation. A company would use the available opportunities to expand, as the workforce would be supported by robots and artificial intelligence, thus optimizing future work. In the second scenario, automation would be replaced by cooperation, being the priority for Industry 4.0. In addition, this scenario would provide the workforce with a voice, making it more involved rather than alienated. Its aim would be to take advantage of the best practices from technology companies, eliminating the tools that disrupt the workforce In the opinion presented by the German Institute for Labor Market Research, the demand for highly skilled employees will grow as a result of the aforementioned transformations, and there will be less demand for workers presenting less advanced qualifications (Spermann, 2016 , Weber, 2016 . Thus, it is of the utmost importance to make efforts to prepare employees for the new challenges imposed by technological changes (Piwowar-Sulej, 2018; Whysall et al., 2019) . That is why it seems justified to describe which employee competencies will be crucial in the future. . It is believed that the Industry 3.0 engineer is a logical, analytical, and systematic person who follows the appropriate procedures and has an innate need to perform tasks properly and to focus on issues rather than people. He/she can work with people, but in a familiar team; he/she does not like changes or new situations; he/she works in a calm and thoughtful manner from start to finish and has the ability to get things done; he/she is a very attentive, polite, well-organized, predictable, and methodical person. In contrast, the Industry 4.0 engineer is an open, active person who likes diversity, both in terms of contact with J o u r n a l P r e -p r o o f people and the tasks performed; he/she can communicate highly technical, detailed information to others with enthusiasm and optimism, evoking positive feelings about the shared ideas; he/she attaches great importance to detail and strives for perfection, ensuring a high quality of work and compliance with standards by following the rules and procedures (Gracel and Stoch, 2019) . In the context of engineers' professional competencies, there is a need for interdisciplinary skills. An engineer should have the technical competencies that allow them to function efficiently in several areas by combining IT knowledge in programming or cybersecurity with an understanding of production processes, automation, robotics, etc. In addition to expanding the scope of professional competencies in various fields, employers expect an engineer to present the respective competencies to production, project, and team management. It is worth pointing out here that the competencies referred to as soft skills constitute the foundation of the above-presented model and cover communication skills with the other employees on one's team as well as the representatives of other departments, flexibility, and the ability to adapt to changing conditions, and thus to initiating and introducing changes in an organization. Moreover, in this model, the problem of sustainability was also addressed. Although the literature studies conducted by Beier et al. (2020) show that there are only a few articles that establish the relationships between Industry 4.0 and sustainability, and Industry 4.0 is often considered to be a disruption in industrial production, "Sustainability and Societal and Environmental Impact" were included among the industry-wide technical competencies. It is worth mentioning here that there has been no common approach in defining the competencies needed for sustainable development (Eizaguirre et al., 2019) . Some authors associate them with the general competencies required in the future (Lambrechts et al., 2013 , Lozano et al., 2017 , while others try to build a list of specific features, such as "1) an appreciation of the importance of environmental, social, political, and economic contexts for each discipline; 2) a broad and balanced foundation knowledge of sustainable development, its key principles, and the main debate within them, including its contested and expanding boundaries; 3) problem-solving skills in a non-reductionist manner for highly complex reallife problems; 4) the ability to think creatively and holistically and to make critical judgements; 5) the ability to develop a high level of self-reflection (both personal and professional); 6) the ability to identify, understand, evaluate, and adopt values conducive to sustainability; 7) the ability to bridge the gap between theory and practice; 8) the ability to practice creatively in interdisciplinary teams; and 9) the ability to initiate and manage change" (Kagawa, 2007, pp. 318-319) . It is noticeable that most of these competencies are soft skills, interpersonal in nature. As indicated in the Introduction, engineers are responsible for introducing product and process innovations such as, e.g., sustainable lean production (Tiwari et al., 2020) . In this way, they not only help to achieve company goals, but they also contribute to the development of a circular economy. A modern engineer is able to operate with a Triple Bottom Line, incorporating financial profitability, environmental integrity ( "a complex set of concepts that describe a healthy natural system" (Payne, 2017, p. 40) ), and corporate social responsibility. They know how to analyze the impacts of a project component on diverse stakeholders. Finally, they can integrate engineering and the arts and humanities. Based on the different lists of competencies presented above, one can conclude that a process of constant learning is needed. Many entities are involved in ensuring the skills desired by employers are available to them. As indicated earlier, employers are responsible for the sustainable development of their employees. The educational system is also of great importance in shaping the competencies of the future. It should create a society of educated and entrepreneurial people. At this point, it is worth noting that a survey conducted in 2015, covering the production industry in Poland, found that in 16% of companies data are still collected manually on paper. In most cases (59% of companies), data are manually entered into a computer system. The Third Industrial Revolution is still a challenge for Polish production plants, let alone Industry 4.0 (76% of companies are only partly automated) (Iwański and Gracel, 2016) . There are many reasons for Poland's technological delay in comparison with the most industrialized countries: late access to Western technologies (not before 1989, i.e., following the communist system's collapse), low labor costs, or inadequate access to capital. In 2018, the group of professionals known as "scientists and engineers" accounted for 7.3% of the active population, whereas in Germany the figure was 7.6%, in the UK it was 10.7%, and in Sweden 11.2% (Eurostat, 2020a) . In addition, labor market analysts have J o u r n a l P r e -p r o o f already identified a gap between employee skills and employer requirements. The problem may result from an absence of developmental thinking among Poles and being locked within the limits of one's learned profession (Zych, 2017) . In the times of digitization, an attractive position on the labor market depends on well-developed digital competencies. In this regard, Poles still lag behind other Europeans. One in five Poles has never used the Internet and only 39% use a computer at work, while in the European Union the respective average percentage amounts to 50%. Only 13% of Poles broaden their knowledge in the field of new technologies (Zych, 2017) . A recently conducted study by the Association of Internet Industry Employers shows that Poland lacks a unified and internally cohesive educational model. Polish universities are not equipped to address the constant changes in communication methods in relation to new media development and the digital world (Kolenda, 2017) . In this context, it is interesting to answer the research question, "do industrial companies practice sustainable HR development towards engineers?" As indicated in the Introduction to this study, the results of three research projects were used to achieve the purpose of the article. The first of them, entitled "The Development The study was conducted by Kantar Polska S.A. using the CATI method, i.e. computerassisted telephone interviews during which an interviewer interacts with a respondent using a J o u r n a l P r e -p r o o f computer equipped with specialized software. Over half of the respondents (57.5%) worked in heavy industry and the rest represented light industry. Thus, it can be adopted that the research reflects -relatively evenly -the two basic branches of industry. In addition, the sample population covered engineers with highly diverse work experience -from individuals just starting out in their careers (24.5%) to those capable of boasting over 20 years of work experience (15%). Women constituted 13% of the respondents. This allowed the researcher to treat the sample as representative, which provides for more reliable inferences based on the results. The analysis also used data from Eurostat and Statistics Poland regarding the practice of employee training in companies. In addition to desk research, the article also presents the preliminary results of research on developing pro-environmental attitudes in the workplace. This research project started in March 2020; however, due to the COVID-19 pandemic, it was only possible to collect (electronically) 50 correctly completed surveys in March and April of 2020. The engineers -Master's degree students studying at Wrocław University of Economics and working in industrial companies -participated in the survey. The article presents only the results that address the problem of employee development in the training process. The survey on the needs of industrial engineers carried out by ASTOR in 2016 found that the main motivators for engineers in their everyday work are as follows: a desire for continuous development and experience, ambitious challenges, various projects, professional passion, and self-fulfillment. At the same time, 68% of the respondents admitted that their company does not offer any development programs for employees; 55% claim that their company does not actively search for employee training. If, however, training courses are J o u r n a l P r e -p r o o f organized, the company finances 85% of the cost. The department manager, the company president, or the owner decide when to send employees for training. In only 8% of cases these decisions are made by an employee individually or after consulting the manager. Therefore (Table 2) . Technical competencies included hard workplace and academic competencies from the ECM as presented above. Personal competencies covered analytical thinking, problem-solving, a creative approach, an openness towards innovation, responsibility, effective handling of the decision-making process, proper time management, a readiness for constant learning, and knowledge transfer. These competencies correspond to levels 1, 2, and 3 in the ECM. Social competencies were associated with soft workplace competencies from the ECM, such as teamwork; interpersonal competencies were connected with personal effectiveness in the ECM; and managerial competencies and communication were included in the academic competencies of the ECM. Analytical and IT competencies were a part of the academic competencies presented in the ECM. According to Polish engineers, the foundation of their professional authority is, above all, their technical knowledge. On the one hand, this is understandable, as technical competencies constitute the profession of an engineer. On the other hand, however, fetishizing these competencies and presenting logical and analytical thinking alone can constitute a barrier to industry innovation (Piwowar-Sulej, 2020b), including product and process innovation that allows the transition from a linear to a circular economy. Cheah and Ng (2012) reached such conclusions, extensively considering the technical optics of engineers as a barrier for implementing the design thinking concept in chemical product development. In this context, it is worth noting that a high level of personal competencies, e.g., a creative approach (89% responses) or social competencies (81% responses), is perceived as positive. As indicated earlier, digital competencies occupy an important place among future competencies (The Gallup Organization, 2010, Davies et al., 2011 , Hecklau et al., 2017 . New areas of competence, such as integrating control systems, programming industrial robot teams, integrating analytical systems in data clouds with local systems, ensuring cybersecurity, or applying artificial intelligence algorithms in automation systems will gain importance. The Internet of Things is now at the heart of companies' digital investment; however, within the next three years the focus will be on a more extensive application of artificial intelligence (Deloitte, 2020) . However, analytical and IT-related competencies were identified by the respondents as being the least important. Slightly more than half of the engineers declared that employers do not expect employees to expand their knowledge on digital technologies, and 12.6% indicated that there is definitely no such expectation. This attitude is reflected in Eurostat statistics. Poland ranks below the EU average in the indicator "Percentage of individuals who have basic or above basic overall digital skills" (Table 3) . Table 3 Percentage of individuals who have basic or above basic overall digital skills (Eurostat, 2020b) Year 2015 The lack of digital competencies is not only a barrier for creating a reputation of being a modern company, but also for the transition from a linear to a circular economy. Although it has been mentioned repeatedly above, it is worth noting again that the digitization of the manufacturing sector will enable the development of environmentally-friendly practices and this can lead to socioeconomic sustainability (Kamble et al., 2018) . The hypothesis can be put forward that having members of Generation C, people born after 1990, enter the job market brings some hope for companies. In the name of this generation, also referred to as "always-on," the letter "C" comes from the English word "connected". This term reflects the role played by the Internet in the life of Generation C. The other words this name may refer to are communicating, content-centric, computerized, community-oriented, always clicking, or change. The research indicates that people from Generation C are not only familiar with technology, but also concerned about environmental problems (Kusá and Piatrov, 2020) . Therefore, they should have and should be willing to develop digital competencies; they should also force employers to comply with the idea of environmental sustainability. whereas health education unrelated to health and safety regulations (concerning, e.g., chronic diseases or lifestyle) was provided in only 1.3% of organizations (Puchalski and Korzeniowska, 2016) . Unfortunately, these studies do not take into account the division into industrial and other companies. The research initiated in March 2020 has been focused on the problem of developing pro-environmental attitudes. In order to create sustainable value for an organization, it is necessary to develop the sustainable competencies of the future (Hart and Milstein, 2003) . The respondents (50 industrial engineers) were asked about the practices followed in the industrial companies they are employed in. As part of these practices, the training courses on pro-environmental issues were specified. Table 4 presents the percentage of responses according to types of companies as well as to groups of respondents. The companies were divided by size and the origin of their capital, while the respondents were grouped according to the position held. As confirmed in many studies (Susan E. , L. D. Zibarras and Coan, 2015 , Pinzone et al., 2016 , Cabral and Lochan Dhar, 2019 , green training has a positive impact on enhancing green awareness and proenvironmental behavior. As Table 4 shows, training on environmental issues is most often provided in very large companies. This is probably associated with ISO 14001 certification. According to the ISO Survey 2018, Poland ranks 146th out of 181 countries in the number of sites per country which have implemented ISO 14001:2015 (Open Text, 2020 . At this point it is worth mentioning that small and medium-sized enterprises (SMEs) constitute a strategic sector of the Polish economy, not only due to their positive impact on regional development, but also because of their share in the growth of gross domestic product (GDP) and the reduction of the unemployment rate (OECD, 2019). The analysis covering Europe highlights the fact that SMEs are responsible for about 64% of industrial pollution, which is in line with their contribution to general production (Constantinos et al., 2010) . Therefore, it is crucial to develop environmental awareness and knowledge in modern technologies in order to enable sustainable development among employees of SMEs. In addition to company size, the origin of capital also matters. There is a clear gap between Polish companies and those with foreign capital. The awareness of training importance in developing pro-environmental behavior is higher among people in managerial J o u r n a l P r e -p r o o f positions. It is difficult to fill in the competence gap in the area of sustainability without providing proper training. Competence in this respect is important because it is the companies that take responsibility for sustainable development worldwide. The The first implication for practice concerns the central role of industrial engineers within the processes of innovation and sustainability. Their potential must be developed so that they can work effectively today and in the future and contribute to the company's sustainable development. In 2035, the demand for emerging technologies alone could even be double that of primary production in 2013 for specific raw materials (Marscheider-Weidemann et al., 2016) . It will be necessary to find substitutes or use resources more efficiency in production and consumption (e.g., proper recycling and purification). This, in turn, requires technological innovation (Bonilla et al., 2018) , and thus, the involvement of industrial engineers. According to a report by Deloitte, 3.5 million jobs will be available in the manufacturing sector, but it is estimated that the existing qualified staff can fill less than half of them. This report reveals that the skills gap could result in as many as 2.4 million vacancies in the period 2018-2028 (Pajula et al., 2018) . These numbers point to the growing gap between available jobs that have to be filled and appropriately qualified personnel to perform these jobs. The report also indicates that in the coming years it will be three times more difficult to recruit employees with digital competences and qualified staff to work in manufacturing processes. These predictions provide substantial grounds for undertaking appropriate development activities in industrial companies. The results identify practical implications not only for training providers and industrial companies, whose HR managers should implement sustainable human resource development. The employees themselves -as the employee 4.0 profile shows -should care about developing their own competences. According to the results, they do not care for the development of their digital competencies. Finally, public schools are responsible for public education. In terms of engineers, this refers to academic teaching, which should prepare engineers for work. The researchers point out that in order to improve management quality in this area, it is also imperative to incorporate into the university curriculum not only the general idea of sustainability, but also the problem of SHRM. Knowledge of modern management methods, including sustainable HR development, will contribute to a greater awareness of future managers and, at the same time, will positively affect the quality of leadership (Opatha, 2019 J o u r n a l P r e -p r o o f Thirdly, this paper focuses on engineers working in Poland. Further research may compare the situation between different countries, for example. The results of such research could provide information that is useful in the decision-making process for investment location and engineers' professional career development. Industrial trainers are also representatives of the professional groups recognized as knowledge workers. Determining how sustainable HR development is implemented in relation to these professional groups could be an interesting research challenge. Finally, a more concerned society and different organizations (public sector, nongovernment institutions) demand that the industrial companies produce in a Triple Bottom Line manner (Sarkis and Zhu, 2018) . However, as indicated in this study, there is a problem with defining sustainable competencies. The challenge for academics is to operationalize the concept of sustainable competencies and design the appropriate measures. Further research should investigate how and under which conditions the particular sustainable competencies contribute to sustainable development. An interesting research area is to identify which teaching methods used at universities and training methods used by professional training providers are the most effective in developing sustainable competencies. The problem of sustainable HRM has not been thoroughly covered as yet due to its complexity and relevance not only for current employers and employees but also for future generations who will be living in the world designed by people working today.
