Within recent years, the literature on employee–CSR relations has grown significantly. However, the research is fragmented throughout various journals and disciplines, and we still lack a comprehensive literature review on the topic to show what we currently know about the employee relationship with CSR, and what we do not know. In this study, we conduct a systematic literature review on employee relations with CSR, based 331 journal articles. We analyze their methodological and theoretical approaches. Based on their key findings, we build a categorization of dominant research findings and their connections. Building on our review, we show how the research has been dominated by a focus on the organizational implementation of CSR and organizational benefits. Employees have been mainly perceived as implementers of top‐down sustainability policies and as mediators towards organizational CSR‐related benefits. We also discuss the need for future research on the more active role of employees in CSR relations, especially bottom‐up change processes and understanding the role of tensions and complexities.
