This study analyzed the impact of Environmental, Social, Governance (ESG) management in public sports organizations on the social values orientation and organizational citizenship behavior of organizational members, and further examined differences based on employment types. To achieve this, a survey was conducted among 404 organizational members working for the Korean Sport and Olympic Committee, local sports organizations and public sports facilities, collecting data on perceived levels of ESG management, social values orientation, organizational citizenship behavior, and employment types. The collected data were analyzed using SPSS and the PROCESS macro to perform moderated mediation analysis. The analysis results indicated that the perceived level of ESG management had a positive impact on the social values orientation of organizational members within public sports organizations, and this social values orientation was found to enhance organizational citizenship behavior. Particularly, considering the differences based on employment types, regular employees showed a more positive response to ESG management compared to non-regular employees, and this was found to have a greater influence on organizational citizenship behavior. This study provides insight into how different members of the organization respond to ESG management by taking into account disparities in employment kinds. It also emphasizes the significance of ESG management for internal culture, values, and member behavior in public sports organizations.
