Four-day week 'an overwhelming success' in Iceland

The trials, in which workers were paid the same amount for shorter hours, took place between 2015 and 2019.

Productivity remained the same or improved in the majority of workplaces, researchers said.

A number of other trials are now being run across the world, including in Spain and by Unilever in New Zealand.

In Iceland, the trials run by Reykjavík City Council and the national government eventually included more than 2,500 workers, which amounts to about 1% of Iceland's working population.
