Trials of a four-day working week in Iceland have been lauded an "overwhelming success", with research revealing the initiative helped increase productivity, and led to an overall improvement in workers' wellbeing.

The trial, run by the icelandic government, were held between the years of 2015 and 2019, with more than 2,500 workers taking part. 

Will Stronge, director of research at Autonomy reveals, "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 has resulted in permanent reductions in working hours for tens of thousands of workers across the country
