23 Aug 2025

Nearly 1.4 million workers in the UK have adopted a full-time four-day workweek between October and December 2024, according to an analysis by the Office for National Statistics (ONS).

This marks an increase of over 100,000 from the same period in 2019 when around 1.29 million people reported working on this schedule.

The trend has been particularly pronounced since the COVID-19 pandemic prompted major changes in work patterns.

They also argue that this model can boost employee motivation and help businesses with recruitment and retention.

The ONS data shows that the percentage of UK workers on a four-day schedule has risen from 9.8% in Q4 2019 to 10.9% today, covering both full- and part-time jobs.
