Two hundred UK companies have signed up to implement a permanent four-day week for all employees at full pay, according to the latest 4 Day Week Foundation data.

The change in UK government has sparked fresh hope among campaigners for wide-spread adoption of the four-day week, ahead of a new trial in the autumn.

Nearly all of the companies that took part in a trial of the four-day working week have decided to keep the policy after finding a strong increase in wellbeing at no cost to productivity.
