Purpose The purpose of this study is to investigate the role of corporate ethical values on the relationship between corporate social responsibility (CSR) and work-related outcomes (organizational commitment (OC), organizational citizenship behavior (OCB) and in-role job performance) in the case of a Greek port logistics management services organization. Design/methodology/approach The field research was carried out by using a structured questionnaire, which was based on empirically validated scales. Employees’ perception of CSR was measured by two dimensions (i.e. social, environmental). Findings Statistical analysis (PLS-SEM) confirms the conceptual framework of the study. More specifically, results revealed the association of both CSR dimensions with CEV and OCB. However, CEV proved to act as a full mediating variable between CSR and OC. Thus, CSR impact on OC is realized only through the development of concrete corporate ethical values. Similarly, CEV influences in role job performance, only through OC and OCB. Research limitations/implications This study is cross-sectional; thus, causality of the relationships under investigation cannot be justified. The cultural context should also be considered, as field research was conducted in a Greek port logistics organization, at a country suffering from deep financial recession. Originality/value Discussion of the importance of corporate ethical values and the underlying mechanisms of organizational policies and practices guiding CSR impact on crucial job-related outcomes.
