Norway Values Personal Life So Much That Leaving at 3 PM Is the Norm: Now, Gen Z Wants the Four Day Week to Arrive Faster

Norwegian companies that slashed weekly working hours by 20 percent without cutting pay maintained full productivity during the country’s first coordinated four-day week trial. The findings, drawn from a six-month pilot involving eleven businesses across Norway and Sweden, were released this week by The Rework and the nonprofit 4 Day Week Global. Researchers from Karlstad University supervised the data collection and analysis.

The pilot operated under the “100-80-100” principle. Employees kept 100 percent of their salary while working 80 percent of their previous hours. Participating firms were required to hit full baseline productivity targets. The model did not mandate a universal four-day structure. Some businesses adopted a four-day week. Others chose a six-hour workday. All variations aimed to compress the same 20 percent reduction into a format that fit operational demands.

The Rework founder Sarah Uldal led the Norwegian arm of the trial, which was conducted in partnership with 4 Day Week Global as the exclusive Norwegian partner. Participating companies entered a planning phase in late 2024 before launching the six-month pilot. During that window, businesses received guidance on eliminating time-wasting practices, restructuring meetings, and redesigning weekly workflows. The goal was to ensure the hour reduction did not simply compress five days of stress into four.

Rising Mental Health Absences Drove Employer Interest

Norwegian employers entered the trial facing a specific and measurable problem. Data from the Norwegian Labour and Welfare Administration shows mental health disorders caused more than 2.2 million lost working days in the fourth quarter of 2024. That category alone accounts for 25 percent of all doctor-certified sick leave in Norway.

The Rework also highlighted survey findings indicating nearly one-third of Norwegian workers report that job demands regularly interfere with private life. Another 27 percent said they had considered quitting specifically to reclaim better work-life balance. These numbers helped recruit the eleven companies that ultimately joined the pilot.

Norway’s Existing Work Culture Provided a Distinct Baseline

The trial unfolded in a country already accustomed to shorter-than-average workdays. Norwegian office employees typically leave work between 3:00 PM and 4:00 PM. Legal norms set the workweek at 40 hours. Actual averages hover closer to 33 hours per week.

This cultural baseline raised a specific research question. Would cutting hours further in a society that already prioritizes early departures produce measurable gains in well-being or retention? Or had Norwegian workplaces already captured most of the benefit that other countries achieved when moving from longer schedules? The Nordic trial was designed in part to test whether the 100-80-100 model translated to a high-trust, high-autonomy work environment.

International Framework Meets Nordic Labor Conditions

4 Day Week Global has now coordinated pilots in more than 20 countries. The organization’s methodology has been tested with over 450 companies and 8,500 employees worldwide. The Norwegian trial operated as a joint effort between the global nonprofit and The Rework.

Academic oversight for the Nordic study came from Lena Lid Falkman at Karlstad University in Sweden. Her team tracked metrics including productivity output, employee well-being, sick leave rates, and staff turnover. The research design mirrored earlier trials conducted in Ireland, Australia, the United States, and the United Kingdom.

The findings arrive as discussions about shorter workweeks gain traction across Europe. Iceland previously completed large-scale trials that informed widespread adoption of reduced-hour contracts. Spain’s government has funded pilot programs in select regions. Belgium now permits workers to compress full-time hours into four days by extending daily shifts.

Skeptical Voices Point to Broader Economic Pressures

Not all commentary surrounding Norway’s work culture aligns with the pilot’s optimistic framing. Some observers note that young Norwegians face housing costs that have doubled since the COVID-19 pandemic. Others point to rising taxes on fuel and an average tax burden approaching 60 percent of income.

The pilot data focuses specifically on company-level outcomes. It does not claim to address broader economic conditions or housing affordability. The research scope remained confined to productivity, well-being metrics, and employee retention within participating firms.

Business Access to the Model Continues

Companies interested in testing reduced hours can now access The Rework Programmet. The digital course offers seven free introductory lessons covering the concept of shorter workweeks and relevant research. Six workshop modules follow for businesses ready to plan implementation. Topics include measuring key performance indicators, removing time drains, designing efficient meetings, and structuring a new weekly schedule.

The program allows companies to work at their own pace without committing to a formal research pilot. It also accommodates businesses that remain uncertain about full adoption but want to explore productivity improvements.
