Intro

A study published earlier this year showed that cutting the working week to four days instead of five significantly improved people's wellbeing. So why hasn’t it become the norm yet? We’re joined by Sofia Bettiza, the BBC’s Global Health reporter, who breaks down all the data we have about the four-day work week, and tells us how reliable it is. Plus we hear about how work culture differs across countries like South Africa and Japan.
