The method used in this study uses correlational quantitative with hypothesis analysis using Process by Andrew Hayes. The results showed a direct relationship between Work-life balance and Job Performance of 0.732 with a P value <0.05. Meanwhile, the indirect estimate value between Work-life balance and Job Performance is Mediation of Psychological Wel-Being of 0.419 with a P value <0.05 which means that Psychological well-being mediates the relationship between Work-life balance and Job Performance. The implications of the research findings indicate the necessity for policies and programs that support nurses' well-being to achieve a balance between professional and personal life. Initiatives aimed at enhancing psychological well-being, such as flexible work schedules and access to mental health resources, can not only improve job performance but also the quality of patient care, leading to a more resilient and efficient healthcare system.
