The influence of Leader Member Exchange on Employee Performance with Job Security, Job Resources and Work Engagement as Mediation at Banda Aceh Tax Office

This study examines the impact of Leader-Member Exchange (LMX) on employee performance, with job security, job resources, and work engagement serving as mediating variables at the Banda Aceh Tax Office. The research population comprises 100 civil servants employed at the Banda Aceh Tax Office, all of whom were included as respondents through the census method. The results of the descriptive analysis indicate that LMX, job security, job resources, work engagement, and employee performance at the Banda Aceh Tax Office are at favorable levels. The direct effect analysis confirms that LMX has impact on job security, job resources, work engagement, and employee performance. Furthermore, job security and job resources are found to positively and significantly influence work engagement, while work engagement, in turn, has impact on employee performance. The findings from the indirect effect analysis reveal that job security and job resources each partially mediate the relationship between LMX and work engagement. Additionally, work engagement is identified as a partial mediator in the relationship between LMX and employee performance. Moreover, job resources and work engagement jointly function as partial mediators in the relationship between LMX and employee performance, reinforcing their significant and positive role in enhancing employee outcomes. This research contributes to management science by reinforcing JD-R Theory and SET Theory SET, emphasizing that leaders play a crucial role in shaping work environments that enhance engagement and performance. It provides empirical evidence that organizations should focus on leadership development, job security, and resource allocation to improve workforce productivity. These insights help refine leadership and organizational behavior theories while offering practical guidance for public sector human resource management.
