A hundred UK companies have signed up to a permanent four-day working week.

The companies have 2,600 staff between them, who will work fewer hours without losing any pay. The development follows a survey of the 70 companies that took part in the 6-month pilot of the four-day week. The survey revealed that 88% of companies found the four-day working week to be working “well” for their business and 95% of companies reported that productivity had either stayed the same or improved since the trial began. The 4 Day Week Campaign group hope this development will be the first step towards a major shift in working practices.
