4 day week UK pilot programme

From June to December 2022, more than 70 UK companies and organisations are trialling a four-day working week, with no loss in pay for employees. It is the biggest ever trial of a four-day week in the world.

More than 3,300 workers, based throughout the UK and representing more than thirty sectors, are receiving 100 per cent of the pay for 80 per cent of the time, in exchange for a commitment to maintain at least 100 per cent productivity.

The pilot is coordinated by 4 Day Week Global, in partnership with leading think tank Autonomy, the 4 Day Week Campaign, and researchers at Cambridge University, Oxford University and Boston College.

The UK programme is running alongside similar pilots in Ireland, the United States and Canada, Australia and New Zealand, and Israel.

Programme Details


The UK employers and workers in the pilot have unparalleled access to the expertise, tools and resources needed to run a smooth and successful trial. The pilot includes:

  • Workshops: delivered by 4 Day Week Global, alongside Autonomy and other companies and organisations that have already successfully implemented a four-day week. This includes online webinars and resources to help with common challenges, pitfalls and misconceptions.

  • Mentoring: from 4 Day Week Global and Autonomy and our network of accredited 4 Day Week Employers. Participants are matched with a mentor that best supports their unique situation.

  • Networking: with other UK participants in the pilot programme. This community acts as a peer-support network to share lessons and experiences.

  • Wellbeing and Productivity Assessment: by a team of world-class academics, as part of a global research project. Our researchers are establishing relevant productivity and worker wellbeing metrics for each participant, and defining what success looks like. These metrics are being monitored throughout the trial, with a confidential impact assessment specific to each organisation produced after the trial, alongside a published report collating the data from all participating companies and employees on an anonymous basis.
