This chapter investigates the effect of employees’ perceptions of corporate social responsibility (CSR) activities of their organization on work-related attitudes. Extant research on CSR and consumer perceptions neglects the core assumption of stakeholder theory that a firm’s long-term value is grounded on the knowledge, abilities, and loyalty of its employees, as well as on its relationships with customers, local community, and other stakeholders. Our field survey is focused on employees of Greek port logistics management services. Building on the argument that employees’ perceptions of CSR activities may be significantly related to workplace attitudes, behaviors, and performance, this chapter examines two CSR aspects (social and environmental) and several work-related attitudes (job performance, employee satisfaction, organizational commitment, OCBO, and OCBI). Our findings highlight that different CSR aspects exert selective direct effects on specific employees’ attitudes, while the managerial implications on firms’ accountability and transparency are also discussed. Even though the study is based on a case study of a port logistics management services organization in Greece, the organizational phenomena under investigation provide interesting evidence that can be applied to other national and organizational contexts.
