U.K. Four-day Workweek Trial Reduced Turnover By 39%

A 15-month trial of a four-day workweek introduced by South Cambridgeshire District Council in the U.K. has revealed overwhelming benefits in favor of the reduced workweek. 

Launched in January 2023, the largest U.K. public sector trial was designed to evaluate whether a shorter working week could maintain or improve productivity without cutting employee wages, and for the most part it did.  

During the trial, university researchers analyzed 24 areas impacting the workplace — including mental health and employee motivation — and found a shorter workweek improved performance in 11 out of the 24 areas. Another 11 areas remained with little or no change, and only two areas experienced worsened performance.  

One of the standout findings was that staff turnover decreased by 39%, which is reported by The Guardian to have saved the council £371,500 ($476,980) primarily from reduced agency staff costs.  

The four-day workweek trial also boosted job applications. The findings revealed that external applications for roles within the council also surged, and Business Insider reports 76% of the applicants cited the four-day workweek as influencing their decision to apply. 

However, the trial was not entirely without its downsides. The project observed a slight decline in rent collection from social housing and a minor increase in the average number of days required to re-let housing stock. 

Despite these minor setbacks, the trial’s success is evident and encouraging. The data shows that organizations and businesses that embrace a four-day workweek could potentially attract top talent and improve employee satisfaction and performance compared to their old work models.  

The U.K.’s positive findings could prove to be influential in the wider global adoption of a four-day workweek as countries including the U.S., Canada, Australia, and Germany explore similar trials.
