BBC RADIO 4 - Analysis

Throughout the first half of the 20th century, the working week gradually got shorter and shorter. As technological advances powered economic growth, workers reaped the gains not just in the form of higher pay, but more leisure time. The economist John Maynard Keynes predicted we'd eventually all be working a 15-hour week. Even in the 1970s the expectation that 8 hour days would be reduced to 6 was widely held across the political spectrum. But this all ground to a halt in the 1980s. In this edition of Analysis Sonia Sodha explores the great leisure mystery: whatever happened to this dream of working less? And why is the idea of a 4-day working week gaining traction on the political left in Britain? What would a society that ditches the long-hours culture, and re-embraces the leisure dream look like, and is it really possible to achieve this without increasing inequality between the haves and have-nots of the labour market?

Recent polling data and election results paint a picture of woe for Britain's two main political parties. Of course both Labour and the Conservatives have suffered periods of decline throughout their history. But arguably never before have both parties been so riven by internal divides and suffered such a loss of public confidence at the same time. Edward Stourton looks to historical precedents for guidance on today's political turmoil and asks if the two parties' decline is now terminal. With Tim Bale of Queen Mary University of London; Lord Lexden, official historian of the Conservative Party; Deborah Mattinson of Britain Thinks; Charlotte Lydia Riley of the University of Southampton; John Sergeant, former BBC Chief Political Correspondent; and Adrian Wooldrige, author of the "Bagehot" column at The Economist.

Paul Johnson discovers why other kinds of further education and training have been neglected, leaving many young people facing much more difficult choices. Yet the needs of the economy and the choices of many shrewd young people suggest non-university education may be heading for revival. Producer: Chris Bowlby Editor: Jasper Corbett
