Being a critical source of competitive advantage to organizations, these workers have many alternatives in the market. Hence, it is of utmost importance for organizations to increase their commitment to their leaders, occupations and organizations so as to increase their performance and intentions to stay. Thus, the present study investigated the roles of perceived justice (procedural and interactional) and empowerment in knowledge workers' commitment to their organizations, leaders and occupations. The proposed conceptual model was tested on 445 knowledge workers working in research and development projects. Analyses with Structural Equation Modeling showed that procedural and interactional justice had significant associations with organizational and supervisory commitment, respectively and perceived empowerment with all commitment foci, namely organizational, supervisory and occupational commitment. Moreover, this group of workers has been found to be more committed to their leaders than to their organizations and occupations. The findings are discussed along with some theoretical and practical implications.EnglishInteractional justiceKnowledge-workersOccupational and organizational commitmentPerceived empowermentProcedural justiceSupervisoryArticle
