Realistically any topic needs to be quite narrow – there are a considerable number of studies on older women and care givieng but little (I have found) on Women at 50+ and work; one question could be if the focus is still on some sort of career or are we planning for retirement?
I think as a background I would refer tothe increase in pension age which for women at 50 means they have potentially another 15- 18 years of work so how do they approach work? I think there is some literature that suggests that men craft their identity from their work; how does this work for women?
