Nature reports on the results of the largest study to date on the impact of a shortened workweek on health and productivity . The study analyzed data from six countries where some companies experimented with transitioning to a four-day workweek without loss of pay. In total, nearly 3,000 people from Australia, New Zealand, the United States, Canada, Ireland, and the United Kingdom participated in the study.
First, the scientists assessed the results of a six-month experiment. The new work schedule reduced employee burnout, increased job satisfaction, and improved overall mental and physical health. The findings were based on an analysis of detailed questionnaires completed by participants before and after the experiment.
"When people are well rested, they work better and more efficiently, and make fewer mistakes," commented economist Pedro Gomes of the University of London.
It's worth noting that before switching to a reduced work schedule, each company spent approximately eight weeks optimizing work processes to maintain productivity. For example, companies often eliminated unnecessary, time-consuming meetings.
In the second phase, the scientists analyzed the results a year after the experiment, as they were concerned that without the novelty of the experience, the positive effects might be diminished. Despite these concerns, well-being levels remained unchanged.
"The fact that over 90% of companies decided to continue the experiment indicates a lack of concern about a decline in productivity and profits," the authors stated. They now want to conduct randomized trials to compare the results under different conditions.
Meanwhile, Poland has announced the launch of a study examining various workforce reduction options. Companies can choose between a six-hour workday, a three-day weekend, or additional vacation days. The project aims to reduce overall working hours by 20% annually and improve work-life balance.
