This study investigates how transformational leadership affects employee performance at the National Transportation Safety Committee (NTSC), focusing on the mediating roles of work engagement and work motivation. A census method was employed, and data were analyzed using structural equation modeling (SEM) based on responses from all 107 NTSC employees in Indonesia. Primary data were collected through a detailed questionnaire covering the entire employee population to ensure comprehensive representation. The findings reveal that transformational leadership positively and significantly influences work engagement, work motivation, and employee performance. Additionally, both work engagement and work motivation significantly enhance employee performance. Mediation analysis indicates that work engagement and work motivation partially mediate the relationship between transformational leadership and employee performance. This study contributes new insights and supports existing literature on transformational leadership, work engagement, work motivation, and employee performance within the NTSC. It recommends that NTSC management clearly communicate the organization’s vision and mission, implement improvements in operational standards to enhance organizational value, and develop policies aligned with the NTSC’s strategic objectives.
