Biggest Trial of Four-Day Workweek Finds Workers Are Happier and Feel Just as Productive

A major study involving 141 companies across six countries found that a four-day workweek improves employee well-being and job performance. The six-month trial showed reduced burnout, increased job satisfaction, and better mental and physical health among workers. Over 90% of companies retained the arrangement after the trial, suggesting no significant drop in productivity. Researchers call for further randomized studies to confirm these positive effects across a broader range of companies.
