Iceland Went To A Four-Day Week In 2019. Six Years Later, Here's The Verdict.
Co-Founder and Chief Data Scientist
In 2019, Iceland made a national shift to a four-day workweek. Six years later, this pilot experiment has become a resounding success, confirming point by point what Generation Z has been arguing for all along: less stress, higher productivity, and a better way to work.
From Pilot Program to National Standard
The Icelandic experiment began in 2015 with a pilot phase involving approximately 2,500 workers—just over 1% of the country's workforce. The response was overwhelming. When 86% of participating employees expressed support for the initiative, the government made it official in 2019.
Today, nearly 90% of Icelandic workers benefit from a reduced workweek of 36 hours, down from 40, with no reduction in pay. It's a complete restructuring of how an entire nation approaches work.
The concerns before implementation were familiar. Productivity would drop. Costs would rise. Service levels would suffer. Both in Iceland and around the world, critics warned of inevitable economic consequences.
The Icelandic reports tell a different story. Productivity remained stable and even increased in certain sectors. The skeptics were wrong.
Mental Health Becomes an Economic Asset
One key to this success lies in improved mental health among workers—a crucial aspect Generation Z has consistently emphasized. The reduction in stress, combined with better work-life balance, had a significant positive impact on employee wellbeing.
But the benefits extended beyond individual workers. One of the most remarkable aspects of the Icelandic experience has been the promotion of greater gender equality. By encouraging men to invest more time in family life, the four-day week contributed to better sharing of domestic and parental responsibilities.
Men, freed from traditional time constraints, could dedicate more hours to their children and actively participate in household tasks. The shorter workweek didn't just change where people spent their time—it changed how families functioned.
Digital Infrastructure Made the Difference
Unlike some countries like Belgium, where the four-day week requires compensating unworked hours with longer days, Iceland maintains salaries and working conditions unchanged despite the reduction in work time. This approach became possible in part through aggressive digitization of businesses and public services.
The Icelandic government invested heavily in digital infrastructure, offering one of the world's most powerful internet connections, even in rural areas. This robust infrastructure supported remote work and maintained productivity despite reduced office presence.
Generation Z, having grown up in a digital environment, adapted naturally to this new mode of work, facilitating a smooth transition to the four-day week. Their digital fluency became an unexpected advantage in making the system work.
A Country Reports Higher Quality of Life
The impact of the four-day week extends far beyond the workplace. Icelanders report significant improvement in their quality of life. They have more time for leisure, families, and friends. Stress related to time constraints has decreased, and people feel generally happier and more fulfilled.
"The reduction of the work week is a great success in Iceland and has changed my family's life," one report noted. "For 90% of Icelanders, the 36-hour week means less stress, more job satisfaction, and more time to enjoy life."
The Icelandic experience now serves as an inspiring example for other countries considering adopting the four-day week. Pilot projects are underway in Germany, Portugal, Spain, and the United Kingdom. Belgium has legislated in favor of the four-day week, though with a compensation system for unworked hours that limits its adoption.
Despite the success of the four-day week, the question of European Union membership continues to divide Icelandic society. Upcoming legislative elections will give citizens the opportunity to weigh in on this crucial subject. Only the Social Democrats and the liberal Reform party openly favor European integration, while the governing coalition parties—ecologists, conservatives, and liberals—oppose it.
By placing individual wellbeing at the heart of its priorities, Iceland has created a more humane and sustainable work model. Generation Z, in defending this cause, helped open the path toward a future where work adapts to the needs of individuals, not the other way around. The Icelandic success proves their predictions were far from utopian—that a profound change in our relationship with work isn't just possible, but achievable.
