In a groundbreaking shift that challenges traditional work paradigms, Germany has recently completed an extensive trial of the 4-day work week. The results have sparked considerable interest across the global business community, with an impressive 73% of participating companies choosing to maintain the shortened schedule. This experiment represents a significant step toward reimagining workplace structures in one of Europe’s economic powerhouses.
The revolutionary “100-80-100” approach
Germany’s experiment, launched in late 2023, implemented the innovative “100-80-100” model—employees receive 100% of their salary while working 80% of standard hours, yet maintain 100% productivity. This approach has already shown promise in countries like the UK, Portugal, and Spain.
The trial unfolded in two distinct phases. Initially, companies spent six months analyzing and optimizing workflows. The subsequent six-month period saw the actual implementation of reduced hours, with employees working 20% less time. Rather than simply cutting hours, the focus remained on enhancing efficiency and maintaining output levels.
Implementation varied significantly across organizations. Some options included:
- Complete closure on Fridays
- Rotating rest days among team members
- Adopting a 4.5-day week structure
- Extending holiday allowances
This flexibility proved crucial to the trial’s success, allowing businesses to adapt the model to their specific operational needs. From tech startups to insurance companies, the diversity of participating sectors demonstrated the model’s versatility across Germany’s economic landscape.

Productivity gains and workplace transformation
Contrary to skeptics’ concerns, productivity remained stable or even increased during the trial period. This success mirrors results from similar experiments worldwide, where reduced hours often correlate with improved efficiency. The German experiment revealed several key factors driving these productivity gains:
| Improvement Area | Implementation Rate | Impact |
|---|---|---|
| Meeting reduction | 60% of companies | Enhanced focus time |
| Digital tool adoption | 25% of companies | Streamlined operations |
| Workflow optimization | Majority of participants | Eliminated inefficiencies |
These efficiency improvements didn’t come at the expense of employee satisfaction. In fact, half of participating workers reported significant improvements in overall well-being, with another 44% noting modest positive changes. The average employee gained 38 minutes of additional sleep weekly, contributing to better health outcomes and increased energy levels.
Perhaps most compelling for business leaders, companies implementing the shortened workweek experienced an 8% increase in employee retention. In today’s competitive talent market, this advantage cannot be overstated.

Reshaping Germany’s work future
While the German Employers’ Association (BDA) hasn’t fully endorsed nationwide adoption, they acknowledge the importance of workplace flexibility and process optimization—central tenets of the experiment. Their position emphasizes the need for customized arrangements through employer-employee negotiation.
The 4-day work week represents more than just reduced hours; it signals a fundamental shift in how we conceptualize productivity and employee value. Germany’s leadership in testing this model positions the country at the forefront of workplace innovation.
The implications extend beyond German borders. As companies worldwide face increasing pressure to attract and retain talent, this successful experiment provides a data-backed alternative to traditional work structures. The results challenge long-held assumptions that more hours automatically equal greater output.
Looking ahead, the balance between work obligations and personal fulfillment continues to evolve. The German experiment suggests that reduced hours might actually enhance both individual well-being and business outcomes—creating a rare win-win scenario in the often-contentious realm of workplace policy.
As of July 2025, Germany’s bold experiment has reframed global conversations about work-life balance and productivity. Whether this marks the beginning of a broader shift remains to be seen, but the data speaks clearly: for many organizations, the 4-day work week delivers measurable benefits without sacrificing business performance.
