Is there an economic case for a four-day working week?

Will Stronge, the co-director of Autonomy, a think tank focusing on the future of work has written a thoughtful piece here about the possibility of a shorter four-day working week.

He argues that for the sake of productivity, the external costs of work-related stress and the poor work-life balance that many people experience, there's a case for a four-day working week. Such an argument was originally propounded in Keynes' essay "Economic Possibilities for Our Grandchildren" published in 1930, and is none the worse for that.

Caroline Lucas from the Green Party lends her support (below) to the idea.
