Employees at 61 companies across Britain worked an average of 34 hours across four days between June and December 2022, while earning their existing salary.The trial is the largest in the world to date, according to Autonomy, a British-based research organisation which published the report alongside a group of academics and with backing from New Zealand-based group 4 Day Week Global.
Staff said their well-being and work-life balance had improved while data showed employees were much less likely to quit their jobs as a result of the four-day week policy. Companies from the marketing and advertising, professional services and charity sectors were most represented in the trial. Some 66% of those participating had 25 or fewer employees, while 22% had 50 or more staff.
