Andrew Barnes is challenging our view of work and how we structure the working week. A year ago the founder of Perpetual Guardian told his staff that he would still pay them for a 5 day week, but they were welcome to talk one day off a week as long as they got all their work done.
Since then he's been spreading the word about the four day working week and the idea of paying not for hours but for productivity.
We talk to him in Paris, where he's just arrived after competing for charity in the Peking to Paris Rally in his car Eleanor, so tells us a bit about that as well.
