Promoting the Sustainability of Organizations: Contribution of Transformational Leadership to Job Engagement. Sustainability 2018, 10, 4109.http://hdl.handle.net/10347/20108The psychology of sustainability highlights the importance of building organizational environments promoting the employees’ well-being, and leaders play an important role in it. Drawing from Kahn’s theory, the purpose of this study is to simultaneously examine the mediating role of task significance, perceived organizational support (POS) and employees’ core self-evaluations (CSE) in the relationship between supervisors’ transformational leadership and job engagement. In order to test the proposed model, a structural equation modelling was performed using the bootstrapping technique in IBM SPSS Amos 23 for Windows. The sample consisted of 320 employees from emergent high-tech and knowledge-based SMEs in Spain. The results supported all the hypotheses posited. By helping employees to find the meaning and significance of their work, making them feel supported by the organization and strengthening their sense of worth and competence, transformational leaders boost job engagement, a key aspect of the human dimension of organizational sustainability. This paper contributes to the psychology of sustainability by advancing knowledge of the mechanisms through which supervisors’ transformational leadership influences employees’ well-being in terms of job engagementeng© 2018 by the authors.
