IS A FOUR-DAY WEEK RIGHT FOR YOUR BUSINESS?

A few years ago, the four-day week was the kind of idea that got filed under ‘interesting but probably not for us’. Today, it is very much for a lot of businesses, and the results are hard to argue with.

The UK’s most recent pilot, which ran across 17 companies and nearly 1,000 employees, ended with 100% of participants choosing to keep the four-day model after the trial finished. A wider international study published in Nature Human Behaviour covering 141 companies across six countries found the same story: 90% continued after the trial ended. Revenue at participating UK companies was up 35% on average compared to the same period in previous years, and staff turnover fell by 57%.

So the question for most business owners in 2026 is less ‘does it work?’ and more ‘could it work for us?’

 

WHAT EXACTLY IS THE FOUR-DAY WEEK?

It’s worth being clear on this, because there are a few different versions doing the rounds. The model that tends to produce the best results is the 100:80:100 principle: 100% of the pay, 80% of the time, in exchange for 100% of the output. The idea is not to squeeze five days of work into four, but to work smarter, cut out the low-value tasks and unnecessary meetings that eat into most working weeks, and protect people’s time and energy more carefully.

That’s different from simply compressing hours, where you’re still doing a 40-hour week but across four longer days. Some businesses go this route and find it works well. Others find it just moves the exhaustion around. The distinction matters when you’re working out which model might suit your team.

 

THE BUSINESS CASE IS STRONG

It is tempting to look at a four-day week as primarily a staff benefit, something you offer to attract and retain good people. And that is true, as it consistently ranks as one of the most valued workplace benefits among employees.

But the productivity data tells a more interesting story. The reason revenue goes up and turnover goes down in most trials isn’t magic. It’s because people who are well-rested, less stressed, and genuinely motivated work better. They make fewer mistakes, take fewer sick days, and are more likely to stay. Over 50 organisations employing more than 1,400 people made the switch in 2025 alone, spanning industries from technology and marketing to healthcare, manufacturing, and retail.

 

THE HONEST CHALLENGES

The four-day week doesn’t suit every business or every role, and it’s worth being straight about that. Client-facing businesses, for example, sometimes struggle with coverage if a significant portion of the team is unavailable on the same day. Industries with tight regulatory requirements or shift-based work face additional complexity in restructuring rotas.

Of the 61 companies in the original UK pilot, 18 eventually returned to a five-day week. That’s not a failure of the concept, but it is a reminder that implementation matters enormously. Businesses that succeeded tended to audit how time was actually being spent before they started, identified the meetings and processes that could be reduced or removed, and involved the whole team in designing the new structure rather than imposing it from above.

 

WHAT CHANGES FOR YOUR OFFICE SPACE?

This is the part of the conversation that doesn’t get nearly enough attention. If your team is shifting to a four-day week, your relationship with your office space is likely to change too.

If Friday becomes the day most people are off, you might find you’re paying for a space that sits empty for a meaningful chunk of the week. Or, if different team members take different days off to maintain coverage, you might find you actually need more flexible arrangements rather than fewer, with people coming and going on different patterns and needing a reliable, professional space when they do come in.

That’s exactly where a flexible workspace comes into its own. Rather than being locked into a fixed amount of space on a long lease, you can dial things up or down as your working patterns evolve. If three days a week is your rhythm, you’re only paying for what you actually use. And if things change again, as they tend to in growing businesses, you’re not stuck.
