The findings suggest that a four-day week significantly reduces stress and illness in the workforce, and helps with worker retention.

Some 71% of employees self-reported lower levels of “burnout”, and 39% said they were less stressed, compared to the start of the trial.

Researchers found a 65% reduction in sick days, and a 57% fall in the number of staff leaving participating companies, compared to the same period the previous year.

Company revenue barely changed during the trial period – even increasing marginally by 1.4% on average for the 23 organisations able to provide data.

In a report of the results presented to UK lawmakers, some 92% of companies that took part in the UK pilot programme (56 out of 61) say they intend to continue with the four-day working week, with 18 companies confirming the change as permanent.

Research for the UK trials was conducted by a team of social scientists from the University of Cambridge, working with academics from Boston College in the US and the think tank Autonomy.

The trial was organised by 4 Day Week Global in conjunction with the UK’s 4 Day Week Campaign, and ran between June and December 2022..
