Iceland Shows the Four-Day Workweek Can Boost Productivity and Health

Imagine working only four days each week but still earning the same pay. That idea became real in Iceland. In 2015, the country initiated a pilot program that allowed public employees to complete their jobs in 36 hours over four days. Workers in offices, schools, and hospitals took part in the first trial. Early reports showed happier staff and no drop in results, so leaders grew the program in 2019.

Today, shorter weeks cover most of Iceland’s public workforce, and the plan is still working. Studies found that productivity stayed level or even rose in some areas, like social services and city maintenance. Researchers link this success to lower stress and better work-life balance. With an extra day to rest, people return to the job feeling fresh, which helps them focus and finish tasks on time.

The change also improved mental health. Surveys show fewer cases of burnout and better overall mood among employees. Families enjoy more time together, and parents can handle chores or appointments without rushing.

Other places are paying attention. Companies in the United States, the United Kingdom, Spain, and Japan have launched their tests. Early feedback looks much the same as Iceland’s results. If the trend continues, the four-day week could soon move from experiment to everyday reality around the world.
