4 day work week experiment is underway in the UK

Missouri State Archives

In the UK, the world’s largest trial of a four-day workweek has begun. More than 3,000 workers across a range of companies — restaurants, banks, health care, retail, and others — will go from five to four work days for the next six months. The workers won’t receive a cut in pay for the shorter week so long as their productivity doesn’t drop. A number of organizations and universities will analyze the results.… Researchers will analyze how employees respond to having an extra day off, in terms of stress and burnout, job and life satisfaction, health, sleep, energy use, travel and many other aspects of life.
