Europe's four-day workweek trials reveal surprising wins and lingering challenges

The four-day workweek has gained traction across Europe, with trials in Sweden, Germany, the UK, and Iceland showing promising results. Many companies report higher employee satisfaction and stable productivity, but not all have stuck with the model long-term. New research also highlights how different age groups respond to flexible work arrangements—and why fairness in unpaid labour remains a pressing issue.

Pilot programmes in several countries have tested the four-day workweek with largely positive outcomes. In Sweden, an 11-company trial in 2023 saw life satisfaction rise by 25% and job satisfaction by 8%. Employees also reported a 13% increase in perceived productivity. Germany's study, involving 45 firms, found reduced burnout rates, while the UK's 61-company pilot—where 56 later extended the model—saw stable revenue and fewer sick days. Many of these businesses, from Malmö and Göteborg to participants in the University of Münster's research, have since kept the shorter week in place.

Yet the approach isn't universal. While 70% of companies in these trials maintained the four-day model, 30% dropped it due to economic or organisational hurdles. Experts argue that rigid, one-size-fits-all solutions often fail, and flexibility in work design remains key to success. Companies must keep adapting workflows to balance productivity with employee well-being.

Stress levels vary sharply between generations. A recent survey found 82% of people suffer from stress-related issues, with Generation Z the hardest hit at 48%. Younger workers often find remote or flexible formats helpful, while baby boomers report 20% lower stress under traditional structures. Common symptoms—headaches, sleep disorders, and restlessness—persist across age groups, underscoring the need for tailored support.

Beyond paid work, inequalities remain. Women still perform two more hours of unpaid labour daily than men, from childcare to household tasks. Addressing this imbalance is critical for achieving a truly fair work-life balance, regardless of the hours spent in the office.

The four-day workweek has proven effective in many cases, but its long-term adoption depends on adaptability. Companies that adjust policies to fit their workforce—whether through fewer meetings, hybrid options, or fairer division of unpaid tasks—see the best results. With stress affecting most employees, the challenge now lies in refining models that work for everyone, from Generation Z to older workers.
