Employment: Happier working a four-day week?

Some employees get paid the same as a five day week, but only work for four.

Supporters say it pays off in the long run as workers are happier and sick days are lower.

Momentum, the grassroots Labour Party group, wants a four-day week for public sector workers included in Labour's manifesto for the next general election.

But is it really feasible for nurses, teachers and others in the public sector? Greg Dawson explores the issue for Politics Live.
