This study examined the impact of subjective well-being on employees involved in corporate social responsibility (CSR) initiatives within professional team sports organizations. Adopting the perspective of self-determination theory, a research model is developed to explore the theoretical connections between perceived CSR, subjective well-being, turnover intention, and creative behavior. The model is tested using partial least squares structural equation modeling (PLS-SEM) with a sample of 263 employees from Taiwanese professional team sports leagues. The findings reveal that employees' perceptions of CSR events have a positive influence on creative behavior while negatively affecting turnover intention. Moreover, subjective well-being mediates the relationship between perceived CSR and both turnover intention and creative behavior. This study contributes to the theoretical understanding of sports CSR by emphasizing the significant role of subjective well-being. Additionally, it offers practical insights for sports organizations to enhance employee well-being and foster positive outcomes through the effective implementation of CSR initiatives.
