An Analysis of Transformational Leadership Styles on Employee Performance with Employee Involvement, Work Environment and Work Culture as an Intervening Variable (Case Study on PT. GKS Management)

This study aims to analyze the influence of transformational leadership on employee performance and examine the role of employee engagement, work environment, and work culture as mediating variables at PT. Gading Kelola Sukses. The study used a quantitative explanatory approach with the Partial Least Squares–Structural Equation Modeling (PLS-SEM) method. The results show that transformational leadership has a positive and significant effect on employee performance, as well as increasing work engagement, work environment, and work culture. However, not all mediating variables showed strong statistical significance, so the mediating role that occurred was limited to partial. These findings confirm that improved performance depends not only on leadership style but also on the psychological, social, and cultural conditions established within the organization. Practically, this research provides recommendations for companies to strengthen cultural values, enhance a supportive work environment, and encourage employee engagement to optimize performance.
