Yesterday was the TUC's annual Work Your Proper Hours Day, when they encourage people to take a full lunch break and go home on time to highlight the amount of unpaid overtime that workers in Britain do.
Their research shows that four out of ten single women in their 30s (39 per cent) do unpaid overtime at work - making them more likely to do unpaid overtime than any other group in the workforce. Single women in every age group are more likely to do unpaid overtime than single men in the same age group, confounding the usual assumption that men put in the longest hours. Just over a quarter (26 per cent) of men in their 30s do unpaid overtime.
I have no evidence, but I would guess that this is true of women working for the church as much as anywhere.
