Top 15 Countries with Legalized 4-Day Work Week in 2025

The move to shorter weeks was once seen as fantasy. By 2025, it’s ink on paper in multiple parliaments. Different paths, same result: more rest days without cutting wages.

1. Belgium – Flexible 4-Day Work Option

Belgium gave staff the right to squeeze their full hours into four days. Fridays suddenly became school runs and grocery days instead of office grind.

2. Iceland – Public Sector Success Becomes Standard

Iceland tested it on thousands of workers. It worked. Now public employees enjoy four-day patterns permanently, while output holds steady.

3. UAE – Federal 4.5-Day Work Week Model

Government offices in the UAE close at noon on Friday. That extra half-day fits cultural rhythm and keeps weekends intact.

4. Spain – 32-Hour Work Week Pilot Expansion

Spain funded businesses to try 32-hour setups. Workers in Madrid cafés talk about finally getting real downtime without a smaller paycheck.

5. Portugal – Nationwide Pilot Programs with Positive Outcomes

Portugal pushed companies to test it. Staff reported less fatigue, managers noticed fewer resignations. A rare win-win in labor law.

6. United Kingdom – Largest Global Trial Success Stories

Britain’s pilot was huge. More than sixty firms, thousands of workers. By 2025, many companies kept it for good, proving it could hold in finance and services.

7. Germany – Growing Trials Across Companies

German unions fought hard. Companies tested the waters. By 2025, reduced schedules spread across manufacturing and tech hubs.

8. Ireland – Collaboration with Global 4-Day Week Movement

Ireland’s pilot tied into international programs. Reports showed calmer workplaces. Lawmakers now face growing pressure to enshrine it nationwide.

9. Australia & New Zealand – Regional Pilots Gaining Momentum

New Zealand’s Perpetual Guardian lit the spark years ago. Australia followed. Today more firms across both countries officially run 4-day setups.

10. South Africa – Africa’s First Major 4-Day Week Pilot

South Africa ran the first large African pilot in 2023. By 2025, retail and service companies adopted it, pulling younger workers into jobs once seen as exhausting.

11. Canada – Corporate Experiments in Reduced Hours

Canada hasn’t legislated yet, but firms stepped up. Staff reported fewer late nights stuck in traffic and more evenings at home.

12. United States – State-Level and Company-Led Pilots

In America, federal law lags. States like California debated bills. Meanwhile, tech firms and creative agencies just did it anyway — and stuck with it.

13. Japan – Flexible Working Hours and Government Support

Japan’s government encouraged four-day options to fight burnout. Banks and electronics firms signed on, though some sectors still resist.

14. Finland & Denmark – Scandinavian Push for Work-Life Balance

Finland and Denmark tested reduced hours inside systems already built for equality. For many workers, it felt like a natural extension, not a radical change.

15. Netherlands & Sweden – Progressive Workplace Experiments

Dutch and Swedish companies ran shorter schedules in schools and hospitals. Teachers and nurses said they felt fresher, patients noticed little change.

Challenges in Implementing a 4-Day Work Week

Some industries can’t just cut a day. Hospitals need full cover. Logistics can’t stop trucks rolling. Small businesses panic about coverage gaps. Yet governments and firms are finding workarounds: split shifts, staggered schedules, and hiring extra staff. Workers argue the trade-offs are worth it — less burnout, fewer sick days, sharper focus.

The Next Step in Work Culture Evolution

The big question now: will this grow into three-day weekends across more economies? Some experts say yes, but only if productivity holds. For people used to endless overtime, walking out of the office on Thursday night feels almost unreal. But in 2025, the hum of Friday mornings now belongs to family breakfasts, errands, or quiet rest.
