<![CDATA[Employee performance is essential to organizational success, particularly in the service industry, where service quality depends heavily on employees’ capabilities and workplace conditions. This study examines the effects of a learning organization culture and the work environment on employee performance, with job satisfaction as a mediating variable among service sector employees in West Jakarta. A quantitative causal approach was employed using an online questionnaire distributed through purposive sampling, resulting in 210 valid respondents. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS. The findings reveal that both a learning organization culture and a positive work environment have significant positive effects on job satisfaction. In addition, learning organization culture, work environment, and job satisfaction each positively and significantly influence employee performance. Job satisfaction also mediates the relationships between learning organization culture, work environment, and employee performance. These results suggest that organizations can improve employee performance by strengthening continuous learning practices, creating supportive working conditions, and enhancing employee satisfaction. The study contributes to the human resource management literature and provides practical guidance for organizations seeking sustainable performance through employee-centered management strategies.]]>
