Teachers are not only required to carry out formal duties but also expected to demonstrate emotional involvement and a strong commitment to their institutions. This study aims to analyze the influence of human resource management practices, perceived organizational support, and work-life balance on teacher commitment, with employee engagement as a mediating variable. The population of this research consists of junior high school teachers in Subrayon 09, Semarang City, with a sample size of 194 teachers who have taught for more than one year. This study employs a quantitative approach using path analysis based on Partial Least Squares (SmartPLS 4). The results show that human resource management practices, perceived organizational support, and work-life balance positively influence employee engagement. Furthermore, employee engagement positively influences teacher commitment. Employee engagement partially mediates the relationship between human resource management practices, perceived organizational support, work-life balance, and teacher commitment. The findings suggest that schools should improve human resource management practices, strengthen perceived organizational support, and maintain work-life balance to enhance employee engagement and teacher commitment, thereby supporting the achievement of organizational goals. / Guru tidak hanya dituntut melaksanakan tugas formal, tetapi juga menunjukkan keterlibatan emosional serta komitmen tinggi terhadap institusi.
