Over the past decade, Iceland has turned a bold experiment into a new normal for most of its workforce, trimming the traditional workweek while keeping pay intact and watching closely for signs of economic fallout that never quite arrived.
A radical shift that started small
The story begins in 2015, when Iceland launched one of Europe’s most ambitious trials of a shorter working week. Around 2,500 employees, just over 1% of the country’s labour force, were invited to cut their weekly hours with no loss of salary.
They did not squeeze 40 hours into four longer days. Instead, they reduced total working time, usually to around 35–36 hours spread over four or four and a half days. Public sector staff, office workers and service employees all took part.
Within four years, new collective agreements meant roughly 90% of Icelandic workers gained the right to shorter hours at full pay.
This shift was not a side perk reserved for tech firms or white‑collar elites. It moved through unions, public administration and major employers, gradually turning into a mainstream labour reform.
Cutting hours, not cramming them
One key difference with other countries lies in how Iceland designed the four‑day week. Belgium, for example, allows employees to compress full‑time hours into four long days. Iceland did the opposite: it chose to cut the number of hours altogether.
That meant workplaces had to rethink how work was done. Managers and staff trimmed unnecessary meetings, tightened agendas and cut back on low‑value tasks. Some offices switched to shorter, more focused daily schedules instead of stretching days into the evening.
The four‑day week in Iceland is less about working harder for longer each day, and more about stripping away inefficiency.
Unions played a central role, negotiating sector‑by‑sector agreements that protected pay levels and clarified expectations. Employers were pushed to measure output and service quality, not hours spent at a desk.

Productivity fears that never materialised
Economists and business leaders worried the move would dent productivity. Early monitoring suggested otherwise. Studies found that output stayed stable and, in some sectors, actually climbed.
Why? Workers reported fewer interruptions, more autonomy and a clearer sense of priorities. Teams redesigned workflows, automated repetitive tasks where possible, and reduced administrative clutter.
- Meetings were shortened or combined
- Emails and internal messaging were streamlined
- Tasks were grouped to cut context‑switching
- Managers spent more time on planning, less on micromanagement
At a national level, headline figures do not point to an economy under strain. Iceland’s unemployment rate sits around 3–4%, markedly lower than the broader European average, and economic growth has remained healthy, helped by tourism, fishing and a growing tech sector.
Iceland’s experience suggests that fewer hours do not automatically mean weaker growth, provided work is redesigned rather than simply reduced.
Wellbeing gains that changed daily life
While productivity stability reassured policymakers, the more striking shifts appeared in people’s lives outside the office. Research by organisations such as Autonomy and the Association for Sustainability and Democracy found that a large majority of participants were satisfied with the shorter week.
Workers reported lower stress, better sleep and fewer signs of burnout. Many used the extra free time for exercise, hobbies or simply unstructured rest. Parents spoke of more time with children; carers found it easier to support elderly relatives without constantly juggling schedules.
Mental health indicators improved in several workplaces. HR departments logged fewer sick days linked to stress or exhaustion. Some companies reported lower staff turnover and easier recruitment, especially in competitive fields where work‑life balance is a selling point.
For many Icelandic workers, one less day on the job translated into more energy, not less commitment, once they returned.
Impact on gender equality
The shorter week also touched on long‑standing inequalities at home. In many countries, women shoulder a larger share of unpaid care work and household tasks. By freeing up time for all employees, the Icelandic model slightly rebalance this load.
Fathers reported being more present with children during the week, not just at weekends. Some couples used the extra time to split chores more evenly, which in turn made full‑time employment more manageable for women.
Iceland, already known for relatively strong gender‑equality policies, used the four‑day week as another lever to reduce the “second shift” of unpaid labour that often falls on women.
A model watched from Berlin to London
Outside Iceland, the experiment has been followed with growing curiosity. Several countries have launched their own pilots, each tweaking the recipe.
| Country | Type of change | Key feature |
|---|---|---|
| Iceland | Reduced hours | 36 hours or less, same pay, broad collective deals |
| Spain | Pilot projects | State‑backed trials in various firms over three years |
| United Kingdom | Voluntary trials | Hundreds of companies tested shorter weeks with full pay |
| Belgium | Compressed hours | Same total hours in four longer days, limited take‑up |
In Spain, a government‑supported programme has involved thousands of workers to assess how shorter weeks affect output and wellbeing. In the UK, private firms from marketing agencies to manufacturing plants have run six‑month trials, many choosing to keep the system once the test period ended.
Belgium’s approach, by contrast, shows that simply reshuffling hours without reducing them does little to change people’s lives. Only a small fraction of employees has chosen that model, highlighting the difference between flexibility and true time reduction.
What a four‑day week actually means in practice
The phrase “four‑day week” hides a range of real‑life arrangements. In Iceland, workers typically lost four to five hours from their weekly schedule, sometimes more, but patterns varied by sector.
Some offices closed entirely on Fridays, concentrating activity from Monday to Thursday. Others kept five‑day coverage but used rotating teams so that each employee enjoyed an extra day off while services stayed open.
For shift‑based roles, such as healthcare and public services, redesigning rotas took longer. Managers had to balance patient needs, safety standards and staff preferences. In several hospitals and care homes, shorter shifts combined with smarter handover routines kept services running smoothly.
The most successful cases involved detailed planning, staff input and careful measurement, not a quick blanket rule.
Key terms: reduced time vs compressed time
Two expressions often get mixed up:
- Reduced time: Fewer total hours per week, usually with the same pay. This is the Icelandic model.
- Compressed time: Same number of hours spread over fewer days, creating longer working days.
The outcomes differ. Reduced time tends to target wellbeing and long‑term sustainability. Compressed time leans more toward flexibility, which can help some workers but risk fatigue for others, particularly parents or people in physically demanding jobs.
Could this work elsewhere?
For countries looking at Iceland, the question is not just whether a four‑day week works in theory, but whether it fits different economies and cultures. Nations with high levels of low‑wage, precarious work might find it harder to maintain pay while cutting hours. Smaller firms may worry about staffing costs.
Yet there are practical steps any employer can test before a sweeping change:
- Run a three‑ or six‑month pilot in one department or team
- Measure output, customer satisfaction and error rates, not just hours
- Agree clear rules on meeting length and focus time
- Involve staff in redesigning processes and schedules
Scenario planning helps. A retail chain, for example, might trial shorter shifts during quieter midweek periods first, then adjust opening hours if performance holds steady. A software firm could shift to “no‑meeting Fridays” as a first step towards a true reduced‑hours model.
There are risks: poorly planned cuts can overload remaining hours, push work into unpaid overtime or damage service quality. Iceland’s experience suggests that success depends on negotiation, transparency and constant adjustment, not just a political slogan or an HR announcement.
For workers and employers facing rising burnout, staff shortages and a tight labour market, the Icelandic experiment offers a detailed case study: a country that shrank its working week, kept its economy running and left most people wanting the shorter schedule to stay.
