Service-oriented organizational citizenship behavior refers to service workers' helping, cooperating, sharing, and donating actions that benefit others at a cost to themselves. Based on ethical climate theory, this research investigates whether corporations adopting environmental, social, and governance (ESG) management enhance service-oriented organizational citizenship behavior (SO OCB) among service employees. A total of 230 surveys were collected from call center workers in the insurance industry, and STATA 14.0 was used to analyze the 204 responses with useable data. The results show that employees' recognized ESG activities enable SO OCB through organizational commitment. Additionally, ESG activity recognition has a positive relationship with self-efficacy and empowerment, which helps service employees regulate external expectations. Thus, this finding is significant for call center workers experiencing emotional labor. Furthermore, the results suggest that firms can contribute to employees' SO OCB by practicing ESG activities. Firms should inform employees of their ESG management efforts as employees' recognition of an ethical climate can enhance their willingness to perform service-oriented behavior. Finally, ESG activity recognition can increase employees’ organizational commitment, an important predictor of employee satisfaction and negative turnover rates.
