When Work Meets Well-Being: Germany’s Four-Day Revolution
In 2025, following a major pilot project that began in late 2023, Germany tested the four-day workweek at scale. The outcome has been striking: 73% of companies in the study have decided not to go back to the traditional five-day week. The research included businesses both large and small, from manufacturing to insurance, technology, media, retail, and education. The trend follows similar experiments in the UK, Spain, and Portugal. Despite Germany’s reputation for rigor and high productivity, many companies now see a future where employee well-being and business performance go hand in hand.
Testing the 100-80-100 Model
The nationwide experiment relied on the “100-80-100” model: 100% of pay, for 80% of the standard working hours, while maintaining 100% of the expected output. Promoted globally by the organization 4 Day Week Global, the model had already delivered positive outcomes in other European countries. The German trial unfolded in two parts: First, a six-month period focused on analyzing and improving work processes; then, six months with the actual four-day schedule, reducing hours by 20%.
Unlike the stereotype, the four-day week didn’t simply mean offices closed every Friday. Some companies rotated which days employees took off, ensuring continued business activity. Others adjusted public holiday schedules, settling on a 4.5-day week. This flexibility allowed firms to adapt the structure to their operational needs.
The range of participants mattered: from micro-businesses to major corporations, and from industry to education, the diversity made the study’s findings relevant across Germany’s economy — not just to a specific sector or business size.
Stable Productivity and Improved Well-Being
What did the results show? Beyond the headline 73% sticking with fewer days, 20% of companies planned only small tweaks, while just 20% said they wanted to return to five days. The remaining 7% remained undecided, underlining that the conversation about work structure is ongoing.
Productivity was closely watched. Overall, it stayed the same or rose slightly. Much of this was attributed to smarter work practices: 60% of participating companies cut back on meeting frequency and duration, and 25% adopted new digital tools. Employees also felt they were more effective, their work rhythm improved, and their perceived workload dropped, thanks to process changes. The reduced hours actually boosted focus and better time use for many.
Employee well-being increased too. Half of employees reported a marked improvement, with 44% noting at least a slight benefit. Workers said they experienced less stress, more motivation, and got about 38 minutes of extra sleep per week, on average. More people reported getting regular exercise. Companies also saw employee retention improve by eight percentage points during the trial.
Flexibility and the Future of Work
Germany’s powerful employer association BDA has stopped short of advocating for a nationwide reduction in hours. Instead, it points to the value of flexibility, efficiency, and negotiated solutions between employers and employees — a reflection of the lessons from the study.
Germany’s pilot has sent a clear message: the world of work is evolving, and the four-day week has moved from theory to a viable alternative for performance and well-being. With the scope of the German study and its careful process, there’s now a strong case for other countries to watch — and maybe, to follow suit.
