Abstract: This study investigates the relationship between work overload and pro‐environmental behavior at work, focusing on the mediating role of organizational identification and the moderating role of corporate social responsibility (CSR). Drawing upon various theories, we propose a moderated mediation model to explain the complex interplay between these variables. Utilizing a 3‐wave time‐lagged research design, data were collected from 224 employees in South Korean companies across three time points. The results of structural equation modeling (SEM) reveal that work overload has a significant negative effect on organizational identification, which in turn positively influences pro‐environmental behavior at work. Furthermore, organizational identification fully mediates the relationship between work overload and pro‐environmental behavior at work. Additionally, CSR moderates the relationship between work overload and organizational identification, mitigating the negative impact of work overload. These findings contribute to the literature by providing a nuanced understanding of the mechanisms and boundary conditions that shape employee pro‐environmental behavior in the workplace. The study offers valuable insights for organizations aiming to promote sustainable practices and foster a green workforce. Practical implications for managers and human resource professionals include the importance of managing work overload, fostering organizational identification, and implementing robust CSR initiatives to support employee pro‐environmental behavior. Limitations and directions for future research are discussed.
