Moonlighting is the practice of doing a second job in addition to one's normal job. Employees are increasingly moonlighting, or taking on additional paid work outside of their principal job, in recent years. While this practice has grown in popularity among employees, it has caused worries among employers, who believe it would have a negative influence on productivity, security, and morale. This phenomenon has the potential to have a substantial impact on an individual's degree of engagement with their primary employer as well as the organization as a whole. Through a thorough evaluation of relevant research, this abstract investigates the impact of moonlighting on organizational involvement. The review focuses on the potential negative effects of moonlighting, such as lower productivity, higher stress and burnout, and less devotion to principal employment. The review does, however, suggest that moonlighting can have a positive impact on organizational involvement, such as greater job satisfaction and skill development. The purpose of this study is to investigate the phenomenon of moonlighting, its causes, and its impact on organizations, as well as potential mitigation techniques. The findings of this analysis offer valuable insights for employers and employees considering moonlighting, indicating that, while there are hazards involved, moonlighting can also give chances for personal and professional advancement. The work is based on a thorough review of the pertinent literature, which includes scholarly publications, books, and reports.
