Quick Answer
Most companies in a UK four-day-week trial kept the shorter schedule afterwards. This is significant because it hints that working fewer days could boost businesses, not just benefit employees. It suggests a potential paradigm shift in how we approach work for improved productivity and well-being.
In a hurry? TL;DR
- 189% of companies in a UK four-day-week pilot continued the schedule, proving it a viable business strategy.
- 2The trial resulted in a 71% reduction in employee burnout and a 57% drop in staff turnover.
- 3Despite reduced hours, company revenue saw a 1.4% average increase during the six-month pilot.
- 4Employees found efficiencies like shorter meetings and streamlined processes to maintain productivity.
- 5The four-day week challenges the idea that more hours always equal more output, highlighting work inefficiencies.
- 6Companies achieved 100% productivity in 80% of time for 100% pay, demonstrating a shift in work culture.
Why It Matters
It's surprising how nearly all companies in a big UK trial opted to keep the four-day week after discovering it works just as well for business.
The 2022 UK four-day-week pilot remains the largest of its kind, revealing that 54 out of 61 participating companies opted to continue the schedule after the trial ended. This 89 per cent retention rate suggests that reducing hours without reducing pay is a viable business strategy rather than just a perk.
Key Figures from the UK Pilot
- Participating Companies: 61
- Total Employees Involved: Roughly 2,900
- Continuing the Schedule: 54 companies (89%)
- Permanent Adoption: 18 companies confirmed an immediate permanent switch
- Revenue Change: 1.4% average increase during the trial period
- Burnout Reduction: 71% of employees reported lower levels of burnout
Why It Matters
The results of this pilot fundamentally challenge the industrial-era assumption that output is a direct linear function of hours spent at a desk. By maintaining 100 per cent pay for 80 per cent time in exchange for 100 per cent productivity, these firms proved that modern work is often bloated with inefficiency.
The Evolution of the Trial
The six-month experiment, which ran from June to December 2022, was organised by 4 Day Week Global in partnership with the think tank Autonomy and researchers at the University of Cambridge and Boston College. Unlike previous small-scale shifts, this trial cut across diverse sectors, including software firms, financial services, healthcare, and even a local fish and chip shop.
Lead researcher Juliet Schor of Boston College noted that the results were remarkably steady. While many expected a drop in productivity or a frantic work pace, the data suggested that employees found smarter ways to work. Meetings were shortened, administrative processes were streamlined, and the morning social lag was replaced by focused deep work.
The Productivity Paradox
The success of the trial rests on the idea of Parkinson’s Law: the concept that work expands to fill the time available for its completion. By tightening the deadline to four days, the fluff inherent in the five-day week—unnecessary emails, over-long briefings, and middle-management check-ins—was naturally edited out.
According to the report from the University of Cambridge, the benefits extended far beyond the office. Sleep improved, physical health scores rose, and the number of staff leaving their jobs dropped by 57 per cent compared to the same period in the previous year.
Real-World Applications
- Creative Agencies: Several London-based firms reported that the extra day of rest led to higher-quality creative output and fewer errors in client work.
- Environmental Impact: The reduction in commuting led to a measurable decrease in carbon footprints for the participating workforce.
- Recruitment Advantage: Companies reported a massive surge in the quality and quantity of job applicants, outcompeting larger firms that insisted on a five-day presence.
Interesting Connections
The term weekend didn't enter common usage until the late 19th century. Before then, workers often took Saint Monday off—an unofficial holiday used to recover from Sunday drinking, which eventually pressured factory owners to formalise shorter hours.
In contrast to the UK's success, some nations like Greece have recently moved in the opposite direction, introducing legislation for a six-day week in specific industries to combat labour shortages. This creates a sharp divide between productivity-led models and volume-led models of growth.
Did companies lose money?
No. On average, company revenue remained stable throughout the trial, and in many cases, it actually grew by a small margin. The cost savings from reduced staff turnover also improved the bottom line.
Did employees have to work longer hours on the four days?
The majority of companies followed the 100-80-100 model: 100 per cent pay, 80 per cent time, in exchange for 100 per cent productivity. They did not cram 40 hours into four days but instead reduced the total hours worked per week.
Can this work for every industry?
While the trial included diverse sectors, client-facing roles or businesses that require 24/7 coverage often use a staggered schedule where different team members take different days off to ensure continuous service.
Key Takeaways
- Retention: 92% of firms originally intended to continue the pilot; 89% followed through.
- Mental Health: Levels of anxiety and fatigue among the 2,900 participants dropped significantly.
- Efficiency: Success relied on cutting out low-value tasks rather than working faster.
- Business Case: Lower turnover and absenteeism make the model financially attractive, even without a productivity spike.
The traditional workweek was designed for a world of physical labour and manual assembly. As the UK pilot proves, in a knowledge-based economy, the most valuable thing an employer can buy is a rested and focused mind.
