More than 60 companies tried a four-day work week and results show why 92% are keeping it

A pilot program testing a four-day work week in the United Kingdom has been hailed as a "resounding success" after employees reported improved well-being and a majority of the participating companies said they would keep the change.

A total of 61 British companies with around 2,900 workers were enrolled in the trial, with employees working an average of 34 hours across four day between June and December 2022, all while keeping their existing salary.

At the conclusion of the six-month trial, 56 of those companies, or 92%, decided to stick with a four-day work week, and 18 did so permanently. 

The findings of this pilot program were released by Autonomy, a British-based think tank that partnered with U.K. academics to conduct the study, backed by 4 Day Week Global, a New Zealand-based campaign that advocates for a four-day work week.
