Corporate social responsibility (CSR) plays an important role in promoting workplace ethics. However, most research has focused on CSRs’ performance or favourable performance-related behaviour outcomes. Little is known about how individual employees perceive CSR and how this affects their ethical behaviour. This research examines how employees' perceived corporate social responsibility (PCSR) facilitates their ethical behaviour. Specifically, we hypothesise that PCSR influences employee ethical behaviour by enhancing employees' organisational commitment. The relationship between employees' commitment and ethical behaviour is contingent on their co-workers' ethical behaviour. The hypothesised relationships were assessed using partial least squares structural equation modelling with a sample of 300 employees from ‘The Ghana Club 100’ firms. Our findings suggest that employee commitment serves as an effective mechanism through which employees' perception enhances their ethical behaviour. The findings also show that the weaker the co-workers' ethical behaviour, the stronger the relationship between employee commitment and ethical behaviour. Both theoretical and practical implications are discussed.

企业社会责任 (CSR) 在促进工作场所道德方面发挥着重要作用。然而，大多数研究都集中在企业社会责任的绩效或与绩效相关的有利行为结果上。关于个别员工如何看待企业社会责任以及这如何影响他们的道德行为，我们知之甚少。本研究考察了员工感知的企业社会责任 (PCSR) 如何促进他们的道德行为。具体来说，我们假设 PCSR 通过增强员工的组织承诺来影响员工的道德行为。员工的承诺与道德行为之间的关系取决于其同事的道德行为。使用偏最小二乘结构方程模型评估假设的关系，样本来自“加纳俱乐部 100 强”公司的 300 名员工。我们的研究结果表明，员工承诺是一种有效的机制，员工的感知可以通过这种机制提高他们的道德行为。研究结果还表明，同事的道德行为越弱，员工承诺与道德行为之间的关系就越强。讨论了理论和实践意义。
