Quick Summary: Key Stats About 4-Day Work Weeks
📊 By the numbers:
- 92% of companies in the UK pilot continued the 4-day work week after trial
- 71% of employees reported lower burnout levels
- 39% reduction in employee stress
- 57% fewer employees leaving companies
- 1,099+ jobs currently available on 4DayJob.com
- 65% increase in applications for 4-day work week positions
The benefits of a 4-day work week are no longer theoretical—they're proven, measurable, and transforming how modern companies operate.
What Is a 4-Day Work Week?
Before diving into the benefits of a 4 day work week, let's clarify what it actually means. There are two primary models:
The 100-80-100 Model (True 4-Day Week)
- 100% of the pay
- 80% of the time (32 hours)
- 100% of the productivity
This is the model most progressive companies adopt. Employees work four days (typically Monday-Thursday or Tuesday-Friday) at 8 hours per day, totaling 32 hours weekly. They receive full pay and benefits.
The Compressed 4-Day Week
- Same 40 hours
- Compressed into 4 days
- Typically 10-hour workdays
While this model offers a three-day weekend, it doesn't reduce total working hours. Employees work longer days (usually 10 hours) to fit a full 40-hour week into four days.
The key difference: The 100-80-100 model focuses on productivity and outcomes rather than hours logged. This guide primarily focuses on the benefits of the true 4-day work week model, though we'll address both where relevant.
The Top Benefits of a 4-Day Work Week
1. Dramatically Increased Productivity
One of the most surprising 4 day work week benefits is that employees actually get more done in less time.
The UK Pilot Results:
The world's largest 4-day work week trial, conducted in the UK in 2022-2023, involved 61 companies and nearly 3,000 employees. The results were remarkable:
- 92% of companies continued the 4-day work week after the pilot
- Revenue increased by an average of 1.4% during the trial
- 71% reduction in employee burnout
- 65% fewer sick days taken
Why does 4 day work week productivity improve?
- Parkinson's Law in action: Work expands to fill the time available. With less time, employees focus on high-impact tasks.
- Fewer meetings: Companies adopting 4-day weeks typically streamline meetings, cutting unnecessary ones.
- Higher energy levels: Well-rested employees make better decisions and work more efficiently.
- Reduced presenteeism: Less time spent "looking busy" and more time on actual output.
Companies like Basecamp and Bolt have reported no drop in productivity—in fact, many saw improvements in key metrics after switching to a 4-day schedule.
2. Dramatically Improved Work-Life Balance
The advantages of a 4 day work week extend far beyond the office. A three-day weekend every week fundamentally changes how employees experience life.
Real-world impacts:
- More time for family, hobbies, and personal development
- Ability to schedule appointments without taking time off
- Reduced stress from work-life conflicts
- Better mental health and life satisfaction
Employees in the UK trial reported:
- 73% improvement in work-life balance
- 40% improvement in sleep quality
- 54% reduction in negative emotions
One employee from the pilot program noted: "I can actually be present for my kids' school events, maintain my fitness routine, and still excel at work. It's not a trade-off anymore."
3. Reduced Burnout and Better Mental Health
Burnout has reached epidemic levels. According to Gallup, 76% of employees experience burnout at least sometimes. The benefits of a 4 day work week directly combat this crisis.
Mental health improvements:
- 71% reduction in burnout levels (UK pilot)
- 39% decrease in stress levels
- Significant reductions in anxiety and depression symptoms
- Improved emotional regulation and resilience
The extra day off provides crucial recovery time. Unlike traditional weekends where Saturday is for errands and Sunday is tainted by "Sunday scaries," a three-day weekend allows for:
- One day for errands/responsibilities
- One day for social activities
- One day for genuine rest and recovery
Dr. Juliet Schor, economist and lead researcher on the 4-day week trials, found that the mental health benefits were among the most significant outcomes, with effects comparable to major therapeutic interventions.
4. Significantly Lower Employee Turnover
Retention is one of the most tangible 4 day work week benefits for employers.
The numbers:
- 57% reduction in employees leaving (UK pilot)
- Companies report 4-day weeks as their #1 retention tool
- 65% more applications for positions advertising 4-day weeks
The cost savings are enormous. Replacing an employee typically costs:
- 50-200% of their annual salary (depending on role)
- 6-9 months of reduced productivity during onboarding
- Lost institutional knowledge
For a company with 50 employees and 15% annual turnover, reducing turnover by even 30% could save $200,000-$500,000 annually.
Real example: Duolingo implemented a 4-day work week and saw their Glassdoor rating jump from 3.9 to 4.5, with retention improving significantly.
5. Environmental Benefits
An often-overlooked advantage of a 4 day work week is its positive environmental impact.
Measurable reductions:
- 20% reduction in commute-related carbon emissions
- Lower office energy consumption (heating, cooling, lighting)
- Reduced traffic congestion
A University of Massachusetts study estimated that a nationwide 4-day work week in the US could reduce carbon footprint by approximately 45 million metric tons annually—equivalent to taking nearly 10 million cars off the road.
For companies with ESG (Environmental, Social, Governance) goals, the 4-day work week provides a meaningful, measurable contribution to sustainability targets.
6. Cost Savings for Companies
While paying full salaries for fewer hours might seem counterintuitive, the 4 day work week benefits create significant cost savings:
Direct savings:
- 20% reduction in office operating costs (utilities, supplies)
- Reduced facilities costs (some companies close offices on Fridays)
- Lower employee turnover costs
- Fewer sick days (65% reduction in UK pilot)
Indirect savings:
- Higher productivity means more output per dollar
- Better employee health reduces insurance costs
- Improved morale reduces management overhead
DuckDuckGo, the privacy-focused search engine, reported that their 4-day week policy cost them nothing in productivity but saved on office expenses and became a competitive hiring advantage.
7. Improved Recruitment and Talent Attraction
In a competitive talent market, the benefits of a 4 day work week create a powerful recruiting advantage.
Recruiting impact:
- 65% increase in applications for 4-day week positions
- Ability to attract top talent from competitors
- Reduced recruiting costs (higher acceptance rates)
- Appeals to younger generations (Gen Z and Millennials)
A 4DayJob.com analysis found that job postings advertising 4-day work weeks receive 2-3x more qualified applications than comparable 5-day positions.
Companies like Bolt (European mobility company) explicitly use their 4-day week policy in recruiting materials, noting it as a key differentiator in attracting engineering talent.
The Potential Drawbacks: 4 Day Work Week Pros and Cons
To provide a balanced view of 4 day work week pros and cons, let's address the legitimate challenges and disadvantages of a 4 day work week.
1. Customer Service Coverage Gaps
The challenge: Businesses requiring 24/7 or extended customer support may struggle with 4-day schedules.
Solutions:
- Staggered schedules (some employees off Monday, others Friday)
- Hybrid models for customer-facing roles
- Enhanced self-service options
- Strategic staffing for peak days
2. Longer Daily Hours in Compressed Models
The challenge: In the compressed 40-hour model, 10-hour days can be exhausting.
Reality check: This isn't the recommended model. The 100-80-100 model (32 hours, full pay) avoids this entirely. Companies forcing 10-hour days miss the point—it's about working smarter, not just rearranging hours.
3. Not Suitable for All Industries
The challenge: Some industries face genuine constraints:
- Healthcare (patient care)
- Manufacturing (production lines)
- Retail (customer demand patterns)
- Hospitality
Reality: Even in these industries, creative solutions exist:
- Healthcare: Rotating 4-day schedules, different models for administrative vs. clinical staff
- Manufacturing: 4-team rotation models
- Retail: Staggered schedules, limited trials in specific departments
Many objections are about imagination, not impossibility.
4. Implementation Challenges
The challenge: Transitioning requires:
- Process redesign
- Cultural shifts
- Technology investments
- Management training
The truth: Yes, it takes work. But UK pilot companies reported the transition was easier than expected, with most adapting within 2-3 months.
Key implementation factors:
- Strong leadership commitment
- Employee involvement in planning
- Willingness to experiment and adjust
- Focus on outcomes over hours

Frequently Asked Questions
Does a 4-day work week mean less pay?
No. The standard 100-80-100 model provides 100% of the pay for 80% of the time (32 hours) while maintaining 100% productivity. Employees receive their full salary and benefits. This isn't a reduction in hours for reduced pay—it's a new way of working focused on efficiency and outcomes rather than hours logged.
What are the main benefits of a 4 day work week?
The primary benefits include:
- Increased productivity (UK pilot showed maintained or improved output)
- Better work-life balance (73% improvement reported)
- Reduced burnout (71% reduction)
- Lower turnover (57% reduction in employees leaving)
- Better mental health (39% decrease in stress)
- Environmental benefits (20% reduction in commute emissions)
- Cost savings for companies
How does 4 day work week productivity compare to 5-day weeks?
Research consistently shows productivity either maintains or improves with 4-day weeks. The UK pilot found revenue increased by 1.4% on average during the trial. Microsoft Japan saw a 40% productivity increase. The key is that shorter timeframes force efficiency, eliminate time-wasting activities, and provide better-rested, more focused employees.
What industries can't do 4-day work weeks?
While implementation varies, few industries are truly incompatible. Challenges exist in:
- Healthcare - but rotating schedules work
- Manufacturing - but 4-team rotations are viable
- Retail/Hospitality - but staggered schedules help
Most "impossible" claims are about unwillingness to redesign processes, not true incompatibility. Creative solutions exist for most industries.
Are 4-day work weeks becoming more common?
Yes, adoption is accelerating rapidly. After the successful UK pilot in 2023, hundreds of companies globally have adopted the model. Countries like Iceland, Scotland, and Spain have national trials. The number of jobs on 4DayJob.com has grown from under 100 in 2020 to over 1,099 in 2026, representing exponential growth.
What's the difference between a 4-day week and a compressed workweek?
A true 4-day week (100-80-100 model) provides 32 hours of work with full pay, focusing on productivity rather than hours. A compressed workweek fits 40 hours into 4 days (10-hour days), offering a 3-day weekend but not reducing total hours. Research shows the 32-hour model provides greater benefits for both employees and employers.
Do 4-day work weeks reduce burnout?
Yes, significantly. The UK pilot found a 71% reduction in burnout levels. The extra day off provides crucial recovery time, allowing employees to truly rest rather than spending weekends on errands and dreading Monday. Stress levels decreased by 39%, and sleep quality improved by 40%.
Conclusion: The Future of Work Is 4 Days
The benefits of a 4-day work week are clear, measurable, and transformative. From the 92% of UK companies that chose to continue after their trial to the 1,099+ jobs currently available, this isn't a fringe experiment—it's the future of work.
The advantages of a 4 day work week extend far beyond happier employees:
- Companies save money and boost productivity
- Environmental impact decreases meaningfully
- Mental health improves dramatically
- Retention and recruitment become easier
While the 4 day work week pros and cons deserve consideration, the overwhelming evidence points to massive benefits with manageable challenges.
