<![CDATA[This study examines the relationships among training, work behavior, work ability, and employee productivity, with the work environment serving as a mediator at PT. Titian Bahtera Indonesia. Using a quantitative explanatory design, primary data were collected through an online questionnaire distributed via Google Forms. Respondents were selected using purposive sampling based on their work experience and involvement in operational activities. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS. The findings indicate that training, work behavior, and work ability positively influence employee productivity. These factors also positively influence the work environment, which contributes to employee productivity. Regarding indirect relationships, the work environment significantly mediates the relationships between training and productivity and between work behavior and productivity. However, the work environment does not significantly mediate the relationship between work ability and productivity. This study contributes to the human resource management literature by integrating individual-related factors and workplace conditions into a single explanatory framework and showing that the work environment's indirect contribution varies across productivity determinants. Managerially, organizations should strengthen relevant training programs, encourage constructive work behavior, develop employee competencies, and maintain a supportive work environment to improve productivity.]]>
