Abstract

The growing global interest in flexible and sustainable work arrangements has led to the widespread experimentation with compressed workweek models, particularly the four-day work week. This meta-analytic review synthesizes empirical findings from diverse industries to assess both the operational efficiency and psychosocial outcomes associated with this evolving work structure. Drawing from over 50 trial implementations across sectors such as healthcare, technology, education, and public administration, the paper evaluates the impact of reduced work hours on productivity, employee well-being, organizational commitment, and customer satisfaction. Quantitative outcomes are analyzed alongside qualitative evidence to explore industry-specific dynamics, cultural adaptations, and managerial concerns. The review highlights key moderators, including sectoral norms, job autonomy, and implementation models, that influence the success or failure of compressed workweeks. The findings provide comprehensive insights for policymakers, organizational leaders, and HR practitioners considering the transition to alternative scheduling frameworks aimed at fostering work-life balance and sustainable performance.
