This study aims to analyze the influence of servant leadership on organizational citizenship behavior (OCB) among hospital employees, considering the mediating roles of organizational trust and organizational commitment. This study employed a quantitative approach using Structural Equation Modeling based on SmartPLS. Data were collected through the distribution of a structured questionnaire to hospital employees, with a total of 198 respondents. The sampling technique utilized a saturated sample method. The results indicate that servant leadership has a positive and significant effect on organizational trust and OCB. Organizational trust was also found to have a positive effect on OCB and mediates the relationship between servant leadership and OCB. Meanwhile, organizational commitment was not found to mediate the relationship between servant leadership and OCB. These findings suggest that organizational trust is a key factor in fostering OCB compared to organizational commitment. Practically, these findings imply that hospital management should develop a service-based leadership style capable of enhancing employee trust. Organizations need to create a transparent, fair, and supportive work environment through open communication, employee empowerment, and an appropriate reward system to enhance OCB.
