From Experiment to Expectation
The four-day work week has moved from a fringe concept to a concrete policy decision at a significant and growing number of organizations. The 2022 UK pilot, which included 61 companies and 2,900 employees across sectors, showed that 92 percent of participating companies maintained the policy after the trial. Revenue held steady or improved. Sick days dropped. Staff turnover fell by 57 percent during the trial period.
Since then, Iceland, Japan, Spain, Belgium, and Portugal have run or legislated four-day work week pilots with broadly similar findings. In the US, companies including Kickstarter and Bolt have adopted variations of the policy. The question for HR teams is no longer "will this ever matter?" but "how does this affect how we hire and retain people?"
The Productivity Evidence
The productivity gains appear to come from two sources. First, the reduction in workdays forces organizations and individuals to eliminate low-value activities: unnecessary meetings, redundant reporting, tasks that exist because they always have. When teams know they have four days to accomplish what they previously did in five, they tend to cut activities that were absorbing time without producing output.
Second, employee wellbeing improvements, specifically better sleep, more time for recovery, and reduced chronic stress, translate into measurably better cognitive performance and lower absenteeism. Organizations that had previously assumed presenteeism was productive found that the opposite was often true.
How It Affects Offer Competitiveness
For companies that have adopted a four-day week, it has become a meaningful component of their compensation package. Candidates who are choosing between two otherwise comparable offers increasingly factor in work schedule flexibility as heavily as they factor in salary differentials of 5 to 10 percent.
Recruiting teams at companies without a four-day week have started to see it surface in candidate conversations. "I have another offer from a company that does a four-day week" is a negotiation point that was rare two years ago and is now occasional in some markets and frequent in others, particularly in technology and digital roles.
What HR Teams Need to Prepare For
If your organization is evaluating or has adopted a four-day week, several operational questions arise. Job descriptions and offer letters need to clearly document the actual expectation: four 8-hour days, four 9-hour days, or 32 hours with no compensation adjustment? For roles that require coverage five days a week, a four-day week requires overlapping schedules or rotation systems. And if your performance management system still rewards hours-at-desk implicitly, the schedule change will create friction. This is an opportunity to revisit whether your performance criteria are measuring the right things.
If You Are Not Adopting a Four-Day Week
Companies that stay on a five-day schedule will increasingly need to compete on other dimensions: superior compensation, faster career progression, more interesting work, stronger team culture, or equity upside. The organizations most likely to succeed at this are the ones that are honest about the tradeoffs they are making and transparent about what they offer in exchange.
