Nature reports on the results of the largest study to date on the impact of a shortened working week on health and productivity . The scientific work analyzed data from six countries in which some companies conducted an experiment to switch to a 4-day working week without losing wages. In total, almost 3,000 people from Australia, New Zealand, the United States, Canada, Ireland, and the United Kingdom took part in the study.
First, the scientists assessed the results of a six-month experiment. The new work schedule reduced the level of employee burnout, increased job satisfaction, and improved overall mental and physical health. The findings are based on an analysis of detailed questionnaires that participants filled out before and after the experiment.
"When people are well rested, they work better and more efficiently, and make fewer mistakes," said economist Pedro Gomes of the University of London.
It is worth noting that before switching to a reduced work schedule, each company spent about eight weeks optimizing work processes so as not to reduce labor productivity. For example, companies often refused unnecessary meetings that take up a lot of time.
In the second stage, the scientists analyzed the results a year after the experiment, as they were concerned that without the novelty of the experience, the positive effect might be reduced. Despite the concerns, the level of well-being remained the same.
"The fact that more than 90% of companies decided to continue the experiment indicates that there is no concern about a drop in productivity and profitability," the authors said. They now want to conduct randomized trials to compare the results in different conditions.
Meanwhile, Poland has announced the launch of a study to examine different formats for reducing work. Companies can choose a six-hour workday, a three-day weekend, or additional vacation days. The project envisages a 20% reduction in overall work time per year and is aimed at improving the work-life balance.
