Job satisfaction, job security, perceived organizational support, and turnover intention are important factors in organizational behavior, especially in the gig economy. This study aimed to identify what influences turnover intentions among Grab driver-partners in Penang. Based on Social Exchange Theory, this study explored how job satisfaction, job security, and perceived organizational support affect drivers’ decisions to stay or leave the Grab platform. A survey was conducted using purposive sampling, distributing 200 questionnaires to Grab drivers in Penang. Out of these, 166 valid responses were collected, giving an 83% response rate. Data were analyzed using SPSS version 30 for reliability and correlation analysis. Results showed that job satisfaction and perceived organizational support both had significant negative relationships with turnover intention, meaning higher satisfaction and support lower the chances of drivers wanting to leave. Although job security was also negatively related to turnover intention, this relationship was not significant. These findings suggest that improving job satisfaction and organizational support can help reduce turnover among gig workers. The study offers practical insights for e-hailing platforms and policymakers and contributes theoretically by applying Social Exchange Theory to gig work. Future research could examine other factors like income stability, work-life balance, or platform policies.
