A multinational study spanning six countries found that transitioning to a four-day workweek, without pay reduction, enhances employee happiness, mental and physical health, and job satisfaction while maintaining productivity. Over 2,800 workers across 141 companies participated in the six-month trial, which included workflow restructuring to ensure operational efficiency. Researchers noted reduced burnout and stress levels among participants, underscoring the potential of condensed workweeks as a strategy for improving workforce wellbeing globally.
