Health Brief: Pilot Program Reveals Benefits of Four-Day Work Week

The nonprofit 4 Day Week Global conducted a six-month pilot of more than 2,900 workers from 61 companies in the United Kingdom from June to December 2022 in which the work week was reduced from a standard 40 hours to 32 hours for the same pay and benefits. At the end of the six-month trial, 39 percent of employees reported less stress and 71 percent expressed lower levels of burnout. Anxiety, fatigue and sleep issues also decreased, while mental and physical health improved. Sixty percent found a greater ability to balance work with home-based responsibilities, and 62 percent found it easier to balance work with social life. Employees were also more satisfied with their finances, relationships and time management.

Company revenue stayed broadly the same over the trial period, rising by 1.4 percent on average. Companies also saw improvements in hiring, absenteeism and resignations, with staff turnover dropping by 57 percent over the trial period. Additionally, 63 percent of businesses offering a four-day week found it easier to attract and retain new talent.
