Four-Day Workweek Statistics 2026: 90% Stay
The four-day workweek moved from experiment to fixture in 2026. In the largest trial to date, 90% of companies kept the four-day schedule after a six-month test across 2,896 employees and 141 organizations. In the UK pilot, burnout fell for 71% of staff while revenue rose 1.4%. Over 200 UK companies have now adopted a permanent four-day week, and 77% of Americans say it would improve their well-being. This report compiles 12 data points from academic studies, government reports, and large-scale pilot programs covering adoption, productivity, health, and worker demand.
The four-day workweek is no longer a fringe idea. Large randomized-style pilots, published peer-reviewed research, and national policy experiments have produced a consistent pattern: reduced hours with full pay tend to hold output steady while improving worker health and retention.
Most of the headline data uses the "100-80-100" model, where staff keep 100% of pay for 80% of the hours, in exchange for maintaining 100% of output. The numbers below show how that trade-off has played out in practice.
This post covers 12 verified statistics drawn from the journal Nature Human Behaviour, the 4 Day Week Global pilot programs, Gallup, the American Psychological Association, and government-backed trials in Iceland, Germany, and the UK. Each figure links to its primary or canonical source.
1. 90% of companies kept the four-day week after the largest trial to date
In the biggest four-day workweek study published so far, 90% of participating companies chose to keep the reduced schedule once the six-month trial ended.
The research, published in Nature Human Behaviour in July 2025 and co-led by sociologist Wen Fan and economist Juliet Schor at Boston College, tracked 2,896 employees across 141 organizations in Australia, Canada, Ireland, New Zealand, the UK, and the US. Workers kept 100% of their pay despite the cut in hours. The study also followed a control group of 562 employees at 12 companies that did not change their schedule.
A 90% retention rate is a strong revealed-preference signal. Companies absorb the cost of a pilot, see the actual effect on their operations, and then decide. Nine in ten deciding to continue suggests the productivity fears that usually block adoption did not materialize.

2. Burnout dropped 0.44 points on a 5-point scale in the 141-company study
Employees in the six-country trial reported a 0.44-point reduction in burnout on a 1-to-5 scale after switching to four days, the largest single effect the researchers measured.
The same Nature Human Behaviour study found job satisfaction rose 0.52 points on a 0-to-10 scale, mental health improved 0.39 points on a 1-to-5 scale, and physical health improved 0.28 points. None of these gains appeared in the control companies that kept a five-day week, which strengthens the case that the schedule change caused them.
The researchers noted the effects were largest for work-related measures like burnout and job satisfaction, smaller for general physical health. That pattern fits the mechanism: a shorter week mostly relieves work-driven strain. When data was collected 12 months after the trial began, the well-being gains remained stable.

3. 71% of UK pilot workers reported lower burnout
In the UK's six-month pilot, 71% of employees said their burnout fell by the end of the trial, and 39% reported feeling less stressed than when they started.
The pilot ran from June to December 2022 with 61 organizations and around 2,900 employees. Research was led by the University of Cambridge with Boston College and the think tank Autonomy. Beyond burnout and stress, workers reported better sleep, less fatigue, and improved mental and physical health.
These are self-reported measures, but the sample size and the consistency across multiple health indicators make the direction hard to dismiss. For employers, lower burnout is not just a wellness metric. It is directly tied to turnover, sick leave, and the cost of replacing experienced staff.

4. Revenue rose 1.4% during the UK trial despite a 20% cut in hours
Companies in the UK pilot saw revenue rise 1.4% on average over the six-month trial, even though staff worked roughly one day less per week.
This is the result that most directly addresses the central objection to a four-day week: that less time means less output and less money. Across the 61 participating firms, revenue held steady and edged upward. Compared with the same period a year earlier, revenue was up 35%, though that figure reflects broader business conditions, not just the schedule.
The 1.4% figure is modest, and it varied widely by company and sector. But the headline is that a 20% reduction in scheduled hours did not produce a corresponding drop in revenue. Most firms recovered the lost time by cutting unproductive meetings and redesigning workflows.

5. Sick days fell 65% and resignations dropped 57% in the UK pilot
Participating UK companies recorded 65% fewer sick days during the trial, and the number of staff leaving fell 57% compared with the same period the previous year.
These two figures are where the four-day week pays for itself on paper. Absenteeism and turnover are among the largest hidden costs in any organization. A 57% drop in resignations means lower recruitment spend, less lost institutional knowledge, and fewer gaps to cover. The 65% reduction in sick days suggests healthier, less-depleted workers.
The retention effect also showed up in the headline outcome: 56 of the 61 companies (92%) chose to continue the four-day week after the pilot, and 18 made it permanent. This was research from the University of Cambridge, Boston College, and Autonomy.

6. 200+ UK companies have made the four-day week permanent
By early 2025, more than 200 UK companies had permanently adopted a four-day week with no loss of pay, covering roughly 5,000 employees, according to the 4 Day Week Foundation.
The vast majority of these firms moved to a 32-hour week. Participants spanned charities, marketing agencies, and technology companies. The announcement, made in January 2025, marked a shift from time-limited pilots toward standing policy at hundreds of organizations.
This matters because permanence is a higher bar than a pilot. A company keeping a four-day week two or three years after the trial has tested it against real business cycles, hiring needs, and seasonal pressure. Crossing 200 permanent adopters in a single country signals the model has moved past novelty in at least some labor markets.

7. Only 8% of US workers actually work a four-day week
Despite the headlines, just 8% of US full-time employees worked a four-day week as of Gallup's measurement, up from 5% in 2020. The large majority, 84%, still work five days, and 8% work six.
Gallup surveyed 12,313 full-time employees for this estimate. The gap between interest and reality is the key story: a four-day schedule remains the exception, not the norm, even as demand for it grows. The 3-percentage-point rise since 2020 is real but slow.
Gallup also found that 44% of on-site employees said they would change jobs for a four-day week. That is a substantial pool of workers treating the schedule as a deciding factor in where they work, which puts pressure on employers competing for talent.

8. 77% of Americans say a four-day week would improve their well-being
In the Bentley-Gallup Business in Society survey, 77% of Americans said a four-day workweek would have a somewhat or extremely positive effect on their well-being, making it the most popular workplace improvement tested.
The survey covered 5,458 US adults. The four-day week beat other proposed changes, including limits on after-hours email, in its perceived impact on personal well-being. This is demand-side data: it measures what workers want, not what they have.
The contrast with the 8% who actually work four days (see stat 7) defines the current moment. Worker demand far outpaces employer adoption. That mismatch is what keeps pilot programs launching and keeps the four-day week in the news cycle year after year.

9. 22% of US employers offered a four-day week in 2024, up from 14% in 2022
The share of US employers offering a four-day workweek climbed to 22% in 2024, up from 14% two years earlier, according to the American Psychological Association's Work in America survey.
That is roughly a 57% relative increase in offerings over two years. The same survey found about 80% of respondents believed they would be happier and remain equally effective on a four-day schedule. APA also cited research finding 42% of full-time employees would accept reduced pay in exchange for the extra day off.
The 42% figure is notable because most pilots use no-pay-cut models. A sizable minority of workers value the time so highly they would trade money for it, which gives employers a low-cost lever if they ever want to offer a four-day week without absorbing the full payroll impact.

10. Iceland trials covered 2,500 workers, and 86% later gained shorter hours
Iceland's reduced-workweek trials from 2015 to 2019 covered around 2,500 workers, over 1% of the country's working population. Afterward, 86% of the Icelandic workforce moved to shorter hours or gained the right to do so.
The trials cut the week to 35 to 36 hours with no loss of pay, analyzed jointly by the think tank Autonomy and the Icelandic research group Alda. Productivity and service delivery stayed the same or improved across most workplaces, while worker well-being rose across stress, burnout, and work-life balance measures.
Iceland is the closest thing to a national-scale proof of concept. Unions used the trial results in collective bargaining, which is how a public-sector pilot turned into shorter hours for most of the country. It is older data, so it is best read as foundational evidence rather than a 2026 snapshot.

11. Germany's 2024 pilot ran across 45 organizations with stable financials
Germany's first coordinated four-day week pilot, launched in February 2024, ran across 45 organizations and reported stable key financial indicators alongside improvements in employee life satisfaction, sleep, and physical activity.
Nearly 40% of the participating firms introduced the four-day week within selected teams rather than company-wide, and many adopted adapted versions rather than a strict model. The pilot was run with 4 Day Week Global, the same body behind the UK and US trials.
The German result echoes the broader pattern: finances held steady while health indicators improved. The high share of partial rollouts is a useful real-world detail. It shows many employers prefer to test the model on one team before committing the whole organization, which lowers the perceived risk of trying it.

12. Attrition fell 57% and 55% of UK workers reported greater work ability
Across the UK pilot, attrition dropped 57% and 55% of workers reported an increase in their ability to do their job, according to 4 Day Week Global's summary of the results.
The "work ability" measure captures whether employees feel capable of meeting the demands of their role. A majority reporting improvement, despite working fewer hours, supports the idea that rested workers are more effective per hour. Paired with the 71% drop in burnout, it points to a workforce that is both healthier and more functional.
These figures come from the same UK program that saw revenue rise 1.4% and 92% of companies continue. Taken together, the retention, health, and output data form a consistent picture rather than a single cherry-picked result.

What these numbers tell us
Taken together, the data shows a model that performs better than its critics predicted and worse than its boosters sometimes claim. The strongest, most consistent effects are on worker health and retention: burnout, sick days, and resignations fall sharply across almost every trial. The effect on revenue and output is real but modest, typically flat to slightly positive, and it depends heavily on companies actually redesigning how they work.
For workers, the gap between demand and availability is the practical takeaway. Around 77% want a four-day week and 44% would switch jobs for one, but only 8% have it. That mismatch means the schedule is increasingly a competitive lever for employers chasing talent, and a realistic ask for workers in tight labor markets.
The trajectory points toward gradual, uneven adoption rather than a sudden shift. Permanent adopters are multiplying, national experiments in Iceland, Germany, the UK, and elsewhere keep producing positive results, and pilots keep converting to standing policy. The five-day week is not disappearing soon, but the four-day week has clearly exited the experimental phase.
The evidence is consistent: a four-day week with full pay reliably improves worker health and retention, holds output roughly steady, and is wanted by far more workers than currently have it.
How Nomad fits in

Frequently Asked Questions
How many companies keep the four-day workweek after trying it?
About 90% of companies keep the four-day week after a trial. In the largest study to date, published in Nature Human Behaviour in 2025 across 2,896 employees and 141 organizations in six countries, 90% retained the schedule. In the separate UK pilot of 61 companies, 56 (92%) continued and 18 made it permanent. High retention rates are the strongest signal that the model works in practice, because companies decide only after seeing the real operational effect.
Does productivity drop on a four-day workweek?
Output generally holds steady rather than dropping. In the UK pilot of 61 companies, revenue rose 1.4% on average over six months despite a roughly 20% cut in scheduled hours. Iceland's national trials found productivity stayed the same or improved across most workplaces. The gains rely on companies redesigning how they work, by cutting unproductive meetings and focusing on outputs instead of hours, rather than simply removing a day.
What percentage of workers want a four-day workweek?
About 77% of Americans say a four-day week would positively affect their well-being, per the Bentley-Gallup survey of 5,458 adults, making it the most popular workplace change tested. Gallup separately found 44% of on-site employees would change jobs to get one, and the American Psychological Association reported 42% would accept reduced pay for it. Demand far exceeds availability: only 8% of US full-time workers actually have a four-day schedule.
How has four-day workweek adoption changed over time?
Adoption is rising steadily but remains low. The share of US workers on a four-day schedule reached 8% from 5% in 2020, per Gallup. The share of US employers offering it climbed to 22% in 2024 from 14% in 2022, per the American Psychological Association. In the UK, over 200 companies had made the four-day week permanent by early 2025, covering roughly 5,000 employees, signaling a shift from pilots to standing policy.
Where do these four-day workweek statistics come from?
The figures here come from primary and canonical sources: the peer-reviewed journal Nature Human Behaviour (the 2025 six-country study led by Boston College), 4 Day Week Global's UK and Germany pilot programs, Gallup and Bentley-Gallup surveys, the American Psychological Association's Work in America survey, and the Autonomy think tank's analysis of Iceland's national trials. Each statistic in this report links to its source, and figures over three years old are labeled by year.
