Career commitment is an important aspect of the workplace that reflects an individual’s willingness to remain in and develop their career. However, various phenomena indicate a decline in career commitment among the workforce. This study aims to examine the effect of job autonomy on career commitment, with employee well-being as a mediating variable, among employees in the mining sector. This study employs a quantitative approach with a nonexperimental design. The sample consisted of 111 employees in the mining sector, selected through accidental sampling. Data were collected using a questionnaire measuring career commitment, job autonomy, and employee well-being, and were subsequently analyzed using mediation regression analysis. The results indicate that job autonomy does not have a significant direct effect on career commitment. However, job autonomy has a positive effect on employee well-being, and employee well-being has a positive effect on career commitment. Furthermore, employee well-being was found to fully mediate the relationship between work autonomy and career commitment. These findings suggest that increased work autonomy only impacts career commitment through improved employee wellbeing. Therefore, organizations need not only to provide work autonomy but also to ensure employee well-being in order to optimally enhance employees’ career commitment
