Should the Working week be 21 hours ?  

The Guardian has an article looking at the success of the four day working week in Utah and efforts to promote shorter working hours - Working week should be 21 hours, says New Economic Foundation.

British workers may be toiling hard to ward off unemployment, but the future could bring an average of only 21 hours a week chained to their desk. A report by the influential thinktank, the New Economic Foundation, says over-consumption, rising unemployment, increasing inequality and deteriorating work-life balance can be tackled by radically altering working life.

Reducing the working week could also defuse the pensions time bomb by ensuring employees are healthy enough to work later in life. Citing the example of Utah, the study shows how the US state's decision in 2008 to place all public-sector workers on a four-day week saved energy, reduced absenteeism and increased productivity. The report argues that 21 hours a week is already close to the average length of time spent in paid employment.
