Assessing the impact of longer workweeks on macroergonomics variables, work-life integration, employee satisfaction,...

Workweek schedules significantly affect employee well-being, as extended hours increase job demands, limit recovery, and disrupt work-life balance for employees. Overtime, prolonged workweeks often disrupt personal routines, increase stress, and diminish overall satisfaction. This study examined the effects of 40-h and 48-h workweeks on Filipino employees' work-life balance, job satisfaction, and productivity. Grounded in the Job Demands-Resources (JD-R) model along with Boundary and Spillover theories, the research explored the impact of extended work hours on employee outcomes. Data were gathered through a 56-item online survey completed by a total of 508 employees. Partial least squares structural equation modeling (PLS-SEM) utilizing SmartPLS 4.0 was used to analyze the relationships between key variables. Results showed that job resources enhance work engagement and effort recovery, aligning with the JD-R model. While effort recovery improves job satisfaction, excessive job demands hinder recovery. Work engagement was found to strongly influence job satisfaction, which in turn positively affected job performance. Additionally, effective boundary management strengthens work-life balance, while spillover effects significantly shape it. However, work-life balance does not significantly impact job satisfaction and instead negatively affects job performance. To mitigate these challenges, organizations should enhance job resources, implement recovery-support initiatives, and establish clear work-life boundaries. Balancing employee well-being with performance expectations fosters a healthier and more productive workplace.
