According to a new study from Saïd Business School at the University of Oxford, a four day working week would actually be a great idea for productivity and employee happiness.
Over six months, associate professor of economics and strategy Jan-Emmanuel De Neve studied the happiness and productivity of 5,000 call centre workers from 20 BT offices.
Workers were asked to rate their happiness every week on a scale from one to five.
There was no real improvement in work quality in the trial, but employees did enjoy having a three day weekend.
De Neve told The Telegraph this is a neurobiological effect of having a shorter working week.
There may not be an immediate change in productivity if a four day week was introduced, but it's definitely a possibility.
More evidence is probably needed before we're likely to see a major adjustment to the way we work. »
