Four-Day Workweek Statistics 2026: Results

90% of companies that piloted a four-day workweek kept it after the trial ended. Burnout rates dropped by 67%, revenue increased by 8% during trials, and 83% of employers said hiring became easier. A 2025 study published in Nature Human Behaviour confirmed significant improvements in mental health, physical health, and job satisfaction - with no loss of productivity.

The four-day workweek has moved from fringe idea to serious policy discussion. Trials across the UK, US, Canada, Australia, New Zealand, and Ireland have produced remarkably consistent results: workers are happier, healthier, and just as productive in four days as they were in five. Companies are keeping the arrangement because it works - for both the bottom line and the workforce.

This post covers 16 statistics from the largest global four-day workweek trials and studies. These numbers span productivity outcomes, employee wellbeing, retention data, and financial results to show what happens when organizations challenge the assumption that more hours means more output.

1. 90% of trial companies retained the four-day workweek after the pilot ended

In the largest coordinated four-day workweek trial to date, involving 141 companies across six countries, 90% chose to keep the shorter workweek after the six-month pilot concluded. The study, conducted by 4 Day Week Global in partnership with researchers from Boston College and Cambridge University, tracked 2,896 participants. The overwhelming retention rate signals that the benefits observed during the trial were not temporary or novelty-driven. Companies found that the productivity, retention, and wellbeing gains were durable enough to justify permanent adoption. Only 10% reverted to a five-day schedule.

2. Burnout dropped by 67% across four-day workweek participants

A multi-country study of four-day workweek trials found a 67% reduction in burnout rates among participating employees. Workers consistently reported feeling less emotionally exhausted, less cynical about their work, and more effective in their roles. The burnout reduction is one of the most significant findings from the trials because burnout is notoriously difficult to reverse once it sets in. The four-day week appears to provide enough recovery time to prevent the accumulation of chronic fatigue that drives burnout. Rest is not a luxury - it is a productivity input.

3. Revenue rose 8% during US and Canadian four-day workweek trials

During four-day workweek trials involving 35 companies and nearly 2,000 employees in the US and Canada, average revenue increased by 8% over the trial period. Compared to the same period in the previous year, revenue was up 37.55%. While some of this growth may reflect broader market conditions, the data firmly refutes the concern that fewer working days means less revenue. Companies did not sacrifice financial performance by giving employees an extra day off. In many cases, the improved focus, reduced burnout, and higher engagement associated with the shorter week actively contributed to revenue growth.

4. 83% of employers said hiring became easier with a four-day workweek

83% of employers who adopted a four-day workweek reported that hiring became significantly easier. In a tight labor market, offering a shorter workweek at the same pay is a powerful competitive advantage. Job postings that advertise a four-day week attract more applicants, higher-quality candidates, and faster time-to-hire. For many organizations, the recruitment benefit alone justifies the policy change. When talent acquisition costs run into thousands of dollars per hire, attracting better candidates more easily produces direct financial returns that compound with every position filled.

5. A 2025 Nature study confirmed the four-day week improves physical and mental health

A large-scale study published in Nature Human Behaviour in 2025 found that a four-day workweek with no reduction in pay led to significant improvements across multiple health dimensions. Burnout decreased by 0.44 points on a 1-5 scale. Job satisfaction increased by 0.52 points on a 0-10 scale. Mental health scores improved by 0.39 points and physical health by 0.28 points. These are meaningful effect sizes in population-level research. The study's publication in one of the world's most prestigious scientific journals lends strong credibility to the four-day workweek movement and moves it from anecdotal success stories to evidence-based policy.

6. 92% of UK pilot companies made the four-day week permanent

Following the UK's coordinated 2022 pilot - the world's largest at the time, spanning 61 firms and roughly 2,900 workers - 92% of participating companies chose to make the four-day workweek a permanent policy. The decision came after a full year of operating under the new schedule. Companies reported that productivity held steady or improved, employee satisfaction increased markedly, and the organizational challenges of the transition were manageable. The 92% permanent adoption rate is among the strongest endorsements any workplace policy has ever received from a controlled trial.

7. 46% of leaders reported stable productivity; 34% said it increased slightly

Among company leaders participating in four-day workweek trials, 46% reported that productivity levels remained stable after the transition, while 34% said productivity "increased slightly." Only a small minority reported any productivity decline. The combined 80% reporting stable or improved productivity directly contradicts the most common objection to the four-day week: that less time means less output. In reality, workers compressed their productive effort into four focused days by reducing time wasted on meetings, social media, and other low-value activities.

8. 41% of workers reported better mental health and 38% improved sleep

Among four-day workweek participants, 41% reported improved mental health and 38% reported better sleep quality. Both findings carry significant implications. Mental health is the leading driver of absenteeism and presenteeism in modern workplaces, and sleep quality directly affects cognitive performance, decision-making, and emotional regulation. When a schedule change simultaneously improves two of the most important inputs to workplace performance, the case for the four-day week moves beyond employee satisfaction into core business strategy.

9. Employee turnover fell from 47% to 29% at Exos after adopting a four-day week

Exos, a US-based performance coaching company, saw its employee turnover rate drop from 47% in 2022 to 29% in 2023 after implementing a four-day workweek. That is a 38% reduction in turnover in a single year. At an average turnover cost of $15,000-$20,000 per employee (and far more for specialized roles), this reduction translates directly to significant savings. The Exos case study is particularly valuable because it provides real company data over a full year, not just short-term trial results. The retention improvement persisted well beyond the novelty period.

10. Absenteeism dropped 65% in four-day workweek companies

Companies operating on a four-day schedule reported a 65% reduction in absenteeism compared to their five-day baseline. Employees who have an extra day for rest, appointments, and personal errands are far less likely to call in sick or take unplanned days off. The 65% reduction is dramatic. It means that most of the absenteeism these companies were experiencing was not driven by genuine illness but by exhaustion, personal logistics, and the inability to manage life responsibilities within a five-day schedule. The extra day off functioned as a pressure valve that eliminated the need for most unplanned absences.

11. 58% of employees would choose a four-day week over a pay raise

When given the hypothetical choice, 58% of employees said they would prefer a four-day workweek over a pay raise. This finding reveals how deeply workers value time. In an era of high living costs and stagnant wage growth, more than half the workforce would trade money for time. For employers, this preference offers an alternative to competing purely on compensation. Offering a four-day week can attract and retain talent without increasing payroll costs - a rare win-win in organizational design.

12. 56% of employees prefer a compressed 40-hour, four-day schedule

56% of employees said they would rather work a 40-hour week compressed into four days than spread across five. This means the appeal of the four-day week is not solely about working fewer hours. Many workers would accept longer daily shifts - 10 hours per day instead of 8 - in exchange for a three-day weekend. The preference for compression suggests that daily commute time, meeting overhead, and startup costs make each additional workday disproportionately expensive in terms of personal time and energy.

13. One London company saw revenue jump 130% during its four-day week trial

BrandPipe, a London-based software company, saw its revenue increase by nearly 130% during its four-day workweek trial, according to data compiled by the 4 Day Week Foundation and Boston College. While this result is an outlier, it demonstrates the upper bound of what is possible when a shorter week catalyzes genuine operational improvements. The company reported that eliminating the fifth day forced teams to prioritize ruthlessly, cut unnecessary meetings, and focus on high-impact work. The constraint became a catalyst for efficiency gains that directly translated to revenue growth.

14. Employee turnover dropped 57% across UK four-day week companies

Across UK companies participating in four-day workweek trials, employee turnover decreased by 57%. Reduced turnover is one of the most financially significant outcomes because replacing an employee typically costs 50-200% of their annual salary when accounting for recruitment, onboarding, training, and lost productivity during the transition. A 57% reduction in turnover effectively cuts one of the largest hidden costs in any organization. Workers who have an extra day of rest each week are less likely to burn out, less likely to job search, and more likely to feel loyal to their employer.

15. Firms adopting the four-day week report productivity increases near 20%

Companies that implemented a four-day workweek with no pay reduction typically reported productivity increases near 20%. This counterintuitive finding reflects Parkinson's Law - work expands to fill the time available. When the time available is reduced, work gets done more efficiently. Teams eliminate unnecessary meetings, reduce social media browsing, streamline communication, and focus on outcomes rather than hours. The 20% productivity increase, combined with the retention and recruitment benefits, makes the business case for the four-day week difficult to dispute.

16. A study of 245 businesses with 8,700+ workers confirmed broad benefits

A comprehensive study analyzing 245 businesses with more than 8,700 workers found that the four-day workweek produced observable benefits across every measured dimension: reduced burnout, improved mental and physical health, and fewer resignations. The scale of this study is important because it moves beyond individual company anecdotes. With nearly 9,000 workers across hundreds of organizations in different industries and countries, the pattern is clear and consistent. The four-day workweek is not a tech industry experiment or a startup perk. It works across sectors, geographies, and company sizes.

The Four-Day Revolution: Less Time, Better Results

The sixteen statistics above tell a remarkably consistent story. Across countries, industries, and company sizes, the four-day workweek produces better outcomes on virtually every metric that matters: productivity holds steady or increases, burnout drops sharply, retention improves dramatically, and even revenue grows. The 90% retention rate among trial companies is perhaps the most telling number. When nine out of ten organizations choose to keep a policy after testing it, the evidence is overwhelming.

What makes these results possible is not magic - it is focus. Companies that adopt a four-day week are forced to examine how time is actually spent. Unnecessary meetings get cut. Communication becomes more intentional. Workers prioritize ruthlessly because they have less time to waste. The constraint of fewer hours drives the efficiency gains that the five-day week never demanded.

The implications extend beyond individual companies. If the four-day week can deliver equivalent or better results in 20% less time, it challenges fundamental assumptions about how work should be organized. The traditional five-day, 40-hour week was designed for factory-era manufacturing. Knowledge work operates on different principles, and the data increasingly suggests it deserves a different schedule.

90% of companies kept the four-day week. 67% burnout reduction. 8% revenue growth. 57% less turnover. The data is in, and it overwhelmingly favors working smarter over working longer.

Make every workday count with smarter capture

The four-day workweek works because it forces teams to eliminate waste and focus on what matters. But even in a four-day schedule, time disappears into manual note-taking, meeting follow-ups, and action item tracking. Every minute spent typing notes is a minute not spent on productive work - and with one fewer day, every minute counts even more.

Voice capture is the natural companion to a compressed workweek. Record meetings with one tap, get instant AI summaries, and let action items extract themselves. No more spending Friday afternoon writing up the week's notes - because there is no Friday.
