World’s biggest 4-day work week trial hailed ‘major breakthrough’
- Largest-ever trial of the four-day work week found that most UK companies participating are not returning to the five-day standard
- With the new schedule, workers reported improvements in everything from stress, fatigue and health to their personal life

The world’s biggest trial of a four-day working week has been hailed a “major breakthrough” after most companies involved said they will keep to the shorter week following the pilot.
The findings of the pilot scheme, conducted in Britain, will be presented to lawmakers on Tuesday as campaigners urge them to give every British worker a 32-hour working week.
The trial saw 61 companies across a variety of sectors in Britain commit to reducing their working hours for all staff by 20 per cent, for six months from June last year.
Crucially, the firms had to make sure there was no reduction in wages for their employees.
At least 56 out of the 61 firms that took part said they plan to continue with the four-day working week, while 18 firms confirmed the policy has become a permanent change.
Just three companies said they have paused the four-day working week in their organisation for the time being.
