Trials of a four-day working week in Iceland have been an “overwhelming success”, say researchers, leading to many employees moving to shorter hours permanently.

The trials took place between 2015 and 2019 and saw workers paid the same amount for working shorter hours. Productivity was found to remain the same or increase in the majority of workplaces.

What’s been said

Will Stronge, director of research at Autonomy, said: "This study shows that the world's largest ever trial of a shorter working week in the public sector was by all measures an overwhelming success.

"It shows that the public sector is ripe for being a pioneer of shorter working weeks - and lessons can be learned for other governments."

Gudmundur Haraldsson, a researcher at Alda, said: "The Icelandic shorter working week journey tells us that not only is it possible to work less in modern times, but that progressive change is possible too."


Trials will now be held in other countries, including Spain and New Zealand.

Large-scale trials have not been piloted in the UK.
