The Impact of Work Overload on Pro-Environmental Behavior at Work: The Mediating Role of Organizational Identification and the Moderating Role of Corporate Social Responsibility

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.
