Sociology professor Juliet Schor studied more than 200 companies with a total of 8,000 employees and found that a four-day workweek yielded better employee retention, less use of sick and personal days, and better outcomes for employees in all 20 well-being metrics measured, including lower stress, lower burnout, and increased physical health. She stated that the optimum arrangement is called 100-80-100, whereby employees produce 100% of their previous output, work 80% of previous hours, and get paid 100% of previous wages; but that this is not achievable for all companies and depends on productivity improvements.
Europe Iceland Two trials in
Iceland between 2015 and 2019 in which working hours were reduced to 35 hours a week without pay reduction for 2,500 workers resulted in "dramatically increased" well-being, and improved work-life balance and stress ratings from employees, measured by a range of indicators such as burnout and perceived stress. Productivity also remained the same, or improved across the majority of all the workplaces, according to UK think tank Autonomy and the Icelandic Association for Sustainable Democracy. While framed as a "four-day week", the trial was for reduced working hours, not necessarily compressed within four days, from 40 to 35 and 36 hours. The study ran two large-scale trials and included more than 1% of Iceland's entire population. The vast majority of the workplaces removed up to three hours from the week, not eight, as would be needed in a four-day week. Agreements to reduce work hours following the trial have led to a reduction of an hour or less. Due to these factors, the study was perceived to be an "overwhelming success", with 86% of the population working in
wage labour later receiving permanent reductions in time spent at work through negotiations.
Spain In 2023, Valencia, Spain, implemented a pilot program scheduling local holidays on four consecutive Mondays, resulting in a four-day workweek for 360,000 workers. This initiative, designed by the left-wing Compromis coalition, showed notable health benefits, including reduced stress and improved air quality due to decreased vehicle emissions. Participants developed healthier habits, although there was an increase in tobacco and alcohol use. The program also positively impacted children's well-being through improved parental work-life balance. Hospitality and tourism saw increased activity, while retail experienced a decline in sales.
United Kingdom As of July 2022, more than 80 UK companies and organisations are recognised as having permanently implemented a four-day working week of fewer than 35 hours, with most doing fewer than 32 hours. gaming studio Big Potato Games; Atom Bank, Leeds-based recruitment agency Charlton Morris; Suffolk-based manufacturing company CMG Technologies, which has been doing a four-day week since 2015; Dorset-based Gungho Marketing; Southampton-based engineering firm Highfield Professional Solutions; and, Edinburgh-based Vault City Brewing. Of the 73 enterprises in the study, 41 firms answered to a survey midway through the plan. Nearly 86% of those polled stated they would continue to follow the four-day workweek guideline when the experiment is over. As 50% of workers claim improved productivity during the period, the Manufacturing Technology Centre (MTC) announced it will permanently provide a four-day workweek to its 820 employees (although with 36 hours instead of 48). According to
Loughborough University, which undertook an external study, the staff's reaction was "overwhelmingly favourable," and for more recent hires, the policies were one of the primary draws. According to survey results, maintaining a "work-life balance" was important to respondents. A first for a UK local body,
South Cambridgeshire District Council (SCDC) opted to proceed with the experiment of a four-day (30-hour) workweek for roughly 470 desk-based employees, who received the same full-time compensation during the trial, planned to last three months starting in January 2023. The decision, according to council leader Bridget Smith, will improve employee welfare. Joe Ryle, director of the 4 Day Week Campaign, said: "The decision by South Cambridgeshire District Council to outline plans to become the first ever UK local authority to trial a four-day week is historic and should be applauded." The district council had planned extend its trial until April 2024 but in June 2023 local government minister,
Lee Rowle, ordered that the council the end the trial because it was not permitted under the Local Government Act. In the face of opposition from Conservative ministers, backed by the
TaxPayers' Alliance, shorter hours are to be introduced in neighbouring
Cambridge city council, and eight other English councils are said to be considering testing shorter working weeks. Glasgow city council was monitoring the pilot programmes and described the four-day working week as "an aspirational position". Regarding the 4 Day Week Global trial organised by think-tank Autonomy and researchers at Boston College and the universities of Cambridge and Oxford, the trial involved 61 companies and almost 3,000 workers The trial's findings suggest that more than 90% of companies that adopted a four-day working week in the UK will continue. Specifically, 18 firms decided to maintain the four-day working week on a permanent basis, and 38 others will continue with the trial. Over the trial period, revenue at participating companies rose on average more than a third compared with the same time in 2021, and the number of staff leaving companies fell significantly. The four-day workweek was discussed in
House of Lords on 5 September 2022 when
Baroness Bennett of Manor Castle questioned if the government is considering the measure especially after
Jacob Rees-Mogg announced a crackdown on flexitime.
Lord Callanan emphasised that government is assessing the measure. According to
Peter Dowd MP, cutting the number of hours worked each week to 32 would provide "every British worker the chance of moving to a four-day week", as he introduced a bill to this effect. The bill lapsed without moving to the committee stages or to the Lords, so it never became law, and would need to be reintroduced before having a possibility of being law. In September 2023 the Scottish government announced the trial of a four-day working week by the end of 2023.
Oceania Perpetual Guardian in New Zealand In New Zealand, trust company Perpetual Guardian announced in February 2018 that it would begin trialing a four-day work week in March 2018. The six-week trial, initiated by founder
Andrew Barnes, saw the company's 240-plus staff nominating a day off each week whilst still receiving full pay. The trial, held in March and April 2018, attracted international media attention. In late March 2018, Barnes said that the trial was going well with staff reporting more time for their families, hobbies, completing their to-do lists and doing home maintenance. The trial, which was tracked and assessed by the
University of Auckland Business School and
Auckland University of Technology, was described as a success and "a total win-win". Perpetual Guardian then extended the four-day work week scheme permanently. The trial saw increased productivity, customer engagement levels, and staff engagement; reduced staff stress levels; and improved work–life balance. The company's revenue remained stable while costs went down, due to less power being used throughout the period. The trial sparked publicity both in New Zealand and internationally. New Zealand workplace relations minister
Iain Lees-Galloway said the trial was "fascinating". The initiative was held up by Barnes as a way of helping to close the
gender pay gap and increase
diversity in the workforce. Barnes also held the scheme up as a potential blueprint for the workplace of the future, ensuring companies were attractive to
millennials and easing Auckland's
traffic congestion. However, while four-day work weeks were deemed a success for most, not everyone involved within the Perpetual Guardian trial was able to adapt, with some reporting feeling increased pressure to complete work within a shorter time frame, particularly around deadlines.
Asia Microsoft Japan Microsoft Japan conducted a trial four-day work week in summer 2019, granting workers paid leave on Fridays. At the same time it cut the length of most meetings from a full hour to half an hour, and capped attendance at five employees. For the duration of the trial, the company reported a 23% reduction in electricity costs. Sales per employee increased 40% during the last year's same period.
Singapore Since 2021,
Raffles Institution in
Singapore has adopted a four-day school week for
junior college students (Years 5 and 6), keeping Wednesdays free of formal lessons. The mid-week "gap day" is used for rest, self-study, co-curricular activities, or enrichment programmes. Introduced after the shift to online learning during the
COVID-19 pandemic, the change aimed to improve students' well-being and time management. According to
The Straits Times, 89% of JC2 and 95% of JC1 students surveyed in 2021 found the gap day beneficial.
A-level results remained unaffected by the new schedule.
North America Utah state government In 2008, employees of the
Utah state government all began working ten-hour days from Monday to Thursday. By closing state government offices on Fridays, the state expected to save on
operating costs such as electricity, heat, air conditioning, and gasoline for state-owned vehicles. Many local governments have had alternative schedules for many years.
K-12 public schools in the United States Due to budgetary problems, public schools in Hawaii closed on 17 Fridays in 2010. In 2002, it was reported that over 100 school districts in rural areas in the United States have changed the school week to a four-day week; most also extended each school day by an hour or more. The changes were often made in order to save money on transportation, heating, and
substitute teachers.
Higher education in the United States In January 2022,
D'Youville University announced a transition to a 4-day, 32-hour work week for all staff and administration without any change to employees pay or benefits. The employees were previously working 37.5 hours per week. The program started as a 6-month trial before eventually being made permanent.
Kickstarter and Union Strike In March 2022,
Kickstarter announced it would experiment with a four-day, 32-hour workweek.
Africa The Gambia civil service In
The Gambia, a four-day work week was introduced for public officials by president
Yahya Jammeh, effective February 1, 2013. Working hours were limited to Monday through Thursday, 08:00 to 18:00, with Friday designated as a day of rest to allow residents more time for prayer and agriculture. This regulation was abolished in early 2017 by his successor, president
Adama Barrow, who decreed a half-day of work on Fridays. == See also ==
