Of the 61 organisations that took part in a six-month UK pilot in 2022, 54 (89%) are still operating the policy a year later, and 31 (51%) have made the change permanent.

More than half (55%) of project managers and CEOs said a four-day week – in which staff worked 100% of their output in 80% of their time – had a positive impact on their organisation, the report found.

For 82% this included positive effects on staff wellbeing, 50% found it reduced staff turnover, while 32% said it improved job recruitment. Nearly half (46%) said working and productivity improved.
