Is the United Kingdom getting closer to introduce a four-day work week?

61 businesses participated in a four-day workweek pilot six months ago with no pay cut. Now, 56 of those organisations plan to keep using the four-day workweek when the experiment is through, with 18 preferring to implement the shift permanently. Participating employees were surveyed before and after, and the results showed that 39% reported feeling less stressed, 40% reported sleeping better, and 54% said it was simpler to balance work and home duties. Additionally, there were fewer sick days taken, and there were 57% fewer staff departures than at the same time last year.

Four-day work week UK trial 

On the four days of the week that they were working, some of the companies participating in the study did extend the working hours for their employees. This is not the objective for many four-day working week purists. Employers who took part in the trial also stated that occasionally, work required to be completed on non-working days. In order to accommodate the four-day workweek, at least one participating enterprise had to hire more employees for a certain area of their operation.  

The trial’s findings are, for the most part, encouraging and shed light on some of the genuine advantages that could possibly follow from the adoption of a four-day workweek. A four-day work week becoming the standard through legislation, however, seems implausible at this time. Although it wasn’t particularly about a four-day working week, the Government’s statement in its December 2022 response to its flexible working consultation that “there is no one-size-fits-all approach to work arrangements” does give some insight into the Government’s overall stance.

The Employment Relations Bill for a four-day week

Employees who have 26 weeks of continuous employment or more may request flexible working arrangements under the law. The Employment Relations (Flexible Working) Bill proposed by the government would grant the right to request flexible working from day one. Employers may only reject a request for flexible working hours for one of eight allowed business grounds. Employers may observe employees citing the trial’s findings in support of any requests for flexible working arrangements involving a four-day workweek. However, employers will still be able to reject the request if one of the business reasons makes it appropriate.

The Success of the Shorter work week

One thing to watch out for is whether the outcomes of this experiment have a greater influence on the decisions that employers make. The vast majority of businesses participating in the largest four-day workweek trial in history chose to keep using the new schedule, which has been welcomed as proof that it might be successful across the UK economy.


The growing global campaign for a shorter workweek and better work-life balance has gained significant momentum, with businesses around the world embracing the idea of a four-day workweek. In the United Kingdom, a recent trial involving 61 organizations showcased the potential advantages of this alternative schedule. Surprisingly, 56 of these companies have decided to continue implementing the four-day workweek, with 18 even considering making it a permanent arrangement. The trial’s findings revealed remarkable benefits, such as reduced stress levels, improved sleep quality, and a simpler way to balance work and home duties. Additionally, there were fewer sick days taken, and there were 57% fewer staff departures than at the same time last year, demonstrating increased productivity and employee satisfaction. As part of the broader four-day week campaign, the United Kingdom’s trial has become a notable example of the positive outcomes that can be achieved through a shorter workweek. Amidst the ongoing pandemic and its impact on working hours, the concept of a four-day workweek has gained traction as a potential solution to promote well-being and better work-life balance. With organizations and campaigners taking part in advocating for a four-day workweek globally, the trial’s success in the United Kingdom further supports the idea that a shorter workweek could be instrumental in creating a more efficient and fulfilling work environment.
