What is a 4-day work week?
A 4-day work week is a working model where employees work four days instead of five while keeping the same pay and productivity expectations.
Unlike a compressed work week, it is not about squeezing five days into four longer shifts. The goal is simple: 100% pay, 80% time, and 100% output through smarter, more focused work.
How does a 4-day work week work?
Businesses usually follow one of two models:
- Reduced hours model - Employees genuinely work fewer hours each week while keeping full pay and output expectations. This is the most common version of a true four-day workweek.
- Compressed schedule model - Employees still work the same total hours but squeeze them into four longer days.
In remote work culture, these setups often rely on async tools like Slack and Notion to keep work moving without constant meetings. Tech firms, agencies, startups, and more UK SMEs are now trialling remote four-day week policy models.
Why the 4-day work week matters for businesses
- Attract better talent - Remote candidates increasingly look for flexibility, not just a bigger payslip. A 4-day work week can make SMEs far more appealing to them.
- Reduce burnout and sick days - More rest often means better morale, fewer “mystery Monday illnesses”, and happier teams.
- Improve productivity - Trials in the UK and Iceland found many businesses maintained or even improved output with fewer working hours. 90% of participating UK businesses opted to continue with it.
- Boost retention - Employees are less likely to leave when work feels sustainable and flexible.
- Look like a modern employer - A remote four-day week policy helps smaller businesses compete with larger companies on culture.
Example of a 4-day work week in a business scenario
Imagine a 12-person digital marketing agency in Manchester testing a Monday-to-Thursday 4-day work week. The team keeps full pay but cuts unnecessary meetings, adds focused deep-work blocks, and shares Friday updates asynchronously through tools like Slack and Notion.
Instead of working longer hours, employees simply work more intentionally. Client deadlines still get met, internal communication becomes clearer, and the business starts seeing fewer sick days and a happier team overall.
For many SMEs, that is exactly why the model is gaining attention.
Difference between a 4-day work week and flexible working
A 4-day work week and flexible working are often linked, but they are not the same thing. A four-day week reduces the number of working days, while flexible working changes when, where, or how employees work.
Let’s take a look at this comparison table.
| 4-day work week |
Flexible working |
|
Employees work fewer days each week, usually with no salary reduction.

Employees choose when, where, or how they work.

Focuses on productivity and reduced working time.
|
Focuses on flexibility around schedules and location.
|
|
Often follows a company-wide policy.

Usually based on a fixed four-day schedule.

May include hybrid work, flexible hours, or compressed schedules.

Common misconceptions about the 4-day work week
- “It just means compressed hours” - Not always. A true 4-day work week reduces working time while keeping pay the same. Working 40 hours across four longer days is a different model entirely.
- “People will get less done” - Many businesses find the opposite happens. Fewer meetings, clearer priorities, and less burnout can lead to better focus and stronger productivity.
- “It only works for tech companies” - Not quite. Retail, healthcare, agencies, and customer service businesses have also tested four-day schedules successfully with the right planning.
- “Everyone gets Friday off” - Not necessarily. Some companies stagger days off across teams to keep customer support and operations running throughout the week.
