Making It Stick: The UK Four-Day Week Pilot One Year On

21st February 2024

One year on from the results of the world’s biggest ever four-day working week pilot which took place in the UK in 2022, companies that took part have reported significant and lasting success.

The report offers new insight into the effects of a four-day week on workers over the longer term, as well as into the strategies used by organisations to fit shorter working hours to their particular circumstances.

Juliet Schor, Professor of Sociology at Boston College:

“The one year results are excellent. Overall results have held and in some cases have even continued to improve. Physical and mental health, and work-life balance are significantly better than at six months. Burnout and life satisfaction improvements held steady. Job satisfaction and sleep problems nudged down a bit, but the bulk of the original improvement remains. 

“The key point is that the strong findings at six months are not due to novelty or short term impacts. These effects are real and long lasting.”

Will Stronge, Director of Research at Autonomy:

“One year on from the results of the UK’s four-day week pilot, virtually every company we’ve spoken to has decided to stick with the four-day week.

“The improvements in physical and mental health, work-life balance, and general life satisfaction, as well as the reductions in burnout found at the end of the trial have all been maintained one year on.
