Most UK firms stick with a four-day working week after taking part in world's biggest trial

February 22, 2024

Most companies involved in the world's largest trial of a four-day working week have made the policy permanent, according to a new report. Of the 61 British companies that took part in a six-month pilot in 2022, at least 54 (89%) said the policy was still in place, while 31 firms (51%) said they had permanently switched to a four-day working week. The companies involved were invited to take part in a follow-up study one year on from the world's biggest trial of a shorter working week to date. "Overall results have held and in some cases have even continued to improve," Schor said in a statement. Job satisfaction and sleep problems nudged down a bit, but the bulk of the original improvement remains."
