Rich, well-educated men and women are working much longer hours than those on low incomes, according to a new working paper. Compared to the 1970s when working hours were at their lowest, the best-educated men in continental Europe, for example, increased their overall work time from just over 8 hours 20 minutes per day (around 5 hours 50 minutes’ paid work and 2 hours 30 minutes’ unpaid housework, shopping and childcare) to 9 hours 10 minutes per day (6 hours 10 minutes’ paid, 3 hours unpaid) – an increase of 20 minutes’ paid work, together with 30 minutes more unpaid work.
