Supervisor performance is a highly interesting topic to study and research in state-owned enterprises, considering its critical role in improving the performance of state-owned companies in Indonesia. However, supervisor performance is hindered by job insecurity, which they experience as long as they do not have job assurance from the company. Therefore, this study aims to investigate the relationship between locus of control and supervisor performance while also examining the moderating role of job insecurity in this relationship within the national electricity company. This study uses an explanatory method with a quantitative approach. The purposive sampling technique was applied to survey 137 respondents, all of whom are supervisors with at least one year of experience in planning, operations, and electrical evaluation at the State Electricity Company in West Java, Indonesia. The data analysis technique is moderated regression analysis, assisted by SPSS version 27 software. The results show that locus of control has a positive and significant effect on supervisor performance (Coef = 0.529, p < 0.05), and job insecurity weakens the relationship between locus of control and supervisor performance (Coef = –0.108, p < 0.05). This study emphasizes the importance of organizations providing job security to supervisors to enhance the performance of state-owned enterprises. Jobs that the organization does not guarantee can reduce the sensitivity of supervisors in developing the organization.
