This study investigates the impact of flexible work arrangements (FWAs) and work-life balance (WLB) on job performance, with perceived autonomy as a mediating factor. The rapid evolution of societal norms and family structures has created a gap between traditional work practices and contemporary workforce needs, leading to increased stress and decreased job satisfaction. This research aims to explore how FWAs and WLB can enhance job performance by fostering perceived autonomy among employees in Malaysia's corporate sector. A quantitative research design was employed, targeting 94 employees from the Cooperative Development Group at ANGKASA, Selangor. Data was collected using structured questionnaires, adapted from established sources, and analyzed using SmartPLS for both descriptive and inferential statistics. The study utilized purposive sampling to ensure the sample accurately reflected the characteristics of the targeted population. Key variables included FWAs, WLB, perceived autonomy, and job performance, with reliability and validity confirmed through Cronbach's Alpha and composite reliability measures. The results demonstrated significant positive relationships between FWAs, WLB, and job performance, mediated by perceived autonomy. Employees with higher perceived autonomy reported better job performance and greater job satisfaction. FWA and supportive WLB policies contributed to reduced absenteeism, lower turnover rates, and enhanced productivity. These findings underscore the importance of implementing flexible work policies to foster a supportive and autonomous work environment, ultimately leading to improved organizational performance and employee well-being.
