Four-day workweek pilot results: productivity, retention and revenue

Autonomy ran the UK pilot, and the Nature Human Behaviour team studied 141 organisations across six countries. This chapter pulls together what those trials and the government-backed pilots in Portugal and Germany found.

Does a four-day workweek work?

In the largest trials so far, most employers kept it. In the UK pilot, 56 of 61 companies were continuing afterwards. In Portugal, 95% of companies rated it positively. In Germany, 73% of organisations said they would continue. The samples were self-selected, so these are results for willing employers, not a forecast for every company.

Continuing and permanent are shares of the 61 companies (56 and 18). Burnout is the share of employees reporting less. Leavers is the fall in staff turnover.

Source: Neowin, August 2019 trial

Most pilot samples are volunteers. Companies that sign up tend to be the ones already likely to succeed, so a high continue rate says less about employers in general.

UK revenue rose 1.4% on average over the trial, weighted by company size.

Our read: Retention is the strongest signal in these trials, because it shows what employers did when the trial ended. Revenue numbers are softer. Pilots were short, firms chose themselves, and nobody ran a clean control. Treat productivity claims as evidence that output held up, not that it grew.

What is changing

  • India: the four labour codes took effect on 21 November 2025, which allows four 12-hour days inside a 48-hour weekly cap.
  • Tokyo: staff can take one weekday off every week from April 2025.
  • South Korea: a subsidy programme for a 4.5-day week runs from 2026, with no law yet.

Rules are moving toward compressed schedules faster than toward shorter hours.

Closed or suspended

  • Confirmed ended: none of the 15 entries.
  • Scotland: the two pilot bodies got extensions of six and two months. The minister ruled out a 32-hour week across government.
  • Spain: take-up fell short of the budget, with 503 workers applying.

A pilot that ends is not always a failure. Many roll into permanent agreements.

Counts are computed from the table rows. Absence from the tracker does not mean absence of a scheme. Not every country was checked.

Our read: The tracker shows law moving slowly and pilots moving fast. Only a handful of places have a rule in force, and most of those change how hours are packed, not how many there are.

Four-day workweek and wellbeing: burnout, stress and sick days

Wellbeing is where the trials agree most. The UK pilot, Scotland and New Zealand all report lower stress, though measures differ.

Caution

Wellbeing gains are real, engagement is less clear

Gallup found on-site workers on four-day schedules reported higher wellbeing but not higher engagement, and slightly higher burnout. Compressing five days of work into four can feel different from working fewer hours.

Source: Gallup, Survey fielded May 8 to 15, 2023

Our read: Wellbeing gains show up in every trial we read, which makes them the safest claim to make. The size of the gain depends on what employees were asked and when. Compare like with like before putting two figures side by side.

Four-day workweek laws and government schemes by country

Few governments have written a four-day week into law. Belgium did in 2022, and India made it possible under new labour codes. Elsewhere it is a government pilot or a scheme for public staff.

A legal right to a four-day week is not the same as a shorter week. Belgium and India both allow fewer days with longer days. Weekly hours stay the same.

Scotland tested a 32-hour week across two public bodies. The minister later ruled out a 32-hour week across the whole government. Sources: Autonomy Institute and Civil Service World.

Our read: Statute is moving toward flexibility in how hours are arranged, not toward fewer hours. If you hire across borders, check which of these two a country actually allows.

Four-day workweek for employers: hours models, cost and global hiring

The UK pilot kept pay level and cut hours, which is why 56 of 61 companies stayed on it. A compressed week costs less to try but gives up much of the wellbeing gain.

EOR guides for cross-border teams

Hiring across borders on a shorter week?

Schedules and overtime rules differ by country. An Employer of Record can set the contract hours locally.

Visit EmployerRecords
Our read: The hours model decides the cost. Reduced hours at full pay shifts cost onto output, so it needs a clear measure of what output means. Compressed hours shifts cost onto fatigue. Pick the model first, then check the local contract rules for each country you hire in.

Four-day workweek tools: six categories teams use

Pilots rarely needed new software. They needed visibility into hours, output and cover. These are the six categories that matter.

Time and scheduling

Rota and shift planners help cover customer-facing hours when staff are off on different days.

Time tracking

Hours data shows whether the shorter week is holding or drifting back to five days of work.

Goal and output tracking

Objective tracking replaces hours as the measure of work, which most pilots relied on.

Async and project tools

Written handoffs keep projects moving when part of the team is out.

Pulse surveys

Short surveys track stress and burnout, the measures most pilots reported.

HRIS and leave management

Records of schedules, leave and pay by country keep contract terms accurate.

Our read: Start with the measures you will report to leadership, then choose tools that produce them. A four-day trial without a baseline for hours, output and wellbeing proves nothing either way.

Four-day workweek outlook: support is ahead of law

Workers back the idea and pilots keep reporting positive results. Rules are changing more slowly, and mostly toward compressed schedules.

Public support is ahead of policy

US adults, Gallup 2023

77%say positive for wellbeing
10 of 15tracked entries still pilots or options
5 of 15law or standing scheme

Source: Gallup, Survey fielded May 8 to 15, 2023

Our read: Expect more pilots, subsidised schemes and compressed-hours rights before any country mandates fewer weekly hours. For employers, the practical path is a time-boxed pilot with clear measures, run in the countries where the rules already allow it.

Methodology and sources

How we built the tracker, which sources we used and what the figures cannot tell you.

Scope

This report covers four-day and shorter-week trials, laws and public schemes, plus worker and employer survey data published through November 2026.

Sources

We use primary reports, government pages and official statistics first. Where a primary page could not be opened, we name the outlet that reported it.

Tracker method

The tracker has 15 entries from 28 named sources. We coded each entry as law or standing scheme, pilot or option, or ended, using the published source only.

Limits

Pilots are mostly self-selected and short. Figures from different trials use different measures, so we do not average them. The tracker is not a full list of countries.

Four-day workweek statistics FAQ

Short answers to the questions employers and workers ask most.

What is a four-day workweek?

It means working four days a week instead of five. Some employers cut hours and keep pay, as in the UK, Portugal and Scotland pilots. Others compress the same hours into four days, which is what Belgium and India allow.

Does a four-day workweek mean a pay cut?

Not in the pilots described here. The UK, Portugal and Scotland pilots kept pay level while hours fell. A compressed week keeps pay and hours the same, so there is no cut either.

How many companies kept the four-day week after the UK pilot?

56 of the 61 companies were continuing at the end of the trial, and 18 had made the change permanent, according to Autonomy.

Is a four-day workweek legal in Belgium?

Yes. Since November 2022, employees can ask to work their hours over four days. The 38-hour week stays, with days of up to 9.5 hours.

Can employers in India run a four-day week?

Yes, within limits. The labour codes in force since 21 November 2025 cap the week at 48 hours, which allows four days of 12 hours. That is a compressed week, not fewer hours.

Did the Microsoft Japan trial prove productivity gains?

Microsoft Japan reported 39.9% higher sales per employee in August 2019. The company later said the rise was not due to the challenge alone, so it is not clean proof.

Does a four-day week reduce burnout?

In the UK pilot, 71% of employees reported less burnout. A Gallup survey of US on-site workers found higher wellbeing but slightly higher burnout, so results depend on how the week is arranged.

How many places have a four-day week law or standing scheme?

In our tracker of 15 entries, 5 are a law or standing scheme and 10 are pilots, options or limited schemes. We did not check every country, so this is not a world count.

How does a four-day week work for teams hired in other countries?

Contract hours, overtime and rest rules differ by country, so the schedule has to match local law. An Employer of Record can write the contract hours for each country.

Why should pilot results be read with caution?

Most pilots used volunteer employers, ran for months, and had no control group. Strong continue rates show willing employers kept going, not that every employer would.
