One irony is that expecting non-parents to work long and late inhibits them from forming families, if that’s what they want. Wilkinson calls this “really, really problematic, especially for the people that were living alone but didn’t want to be living alone, and were trying to develop relationships, because that’s the stuff that gets in the way of being able to go on a date or to be developing partnerships”. It’s also hard on people undergoing complex fertility treatments, who might need flexibility for these but feel that their managers wouldn’t understand.
