This study aims to analyze the influence of servant leadership and psychological empowerment on organizational citizenship behavior (OCB) with job satisfaction as a mediating variable at PT Metrocom Global Solusi. A quantitative approach was used with a saturated sample technique, involving the entire population of 133 employees as respondents. Data were collected through questionnaires and analyzed using the Partial Least Squares-Structural Equation Modeling (PLS-SEM) method. The results indicate a positive and significant effect of servant leadership on OCB and job satisfaction. Psychological empowerment shows a positive and significant influence on job satisfaction and OCB. Job satisfaction demonstrates a positive and significant effect on OCB. Job satisfaction can act as a mediating variable between servant leadership and psychological empowerment toward OCB.
