Correct, I've also chosen in my early career to work in female dominated industries and I have also chosen to work in male dominated industries working as Labourer, truck driver, store hands moving across to direct care work in disability, human services etc.
Work is work and from experience there is no difference to how work place stress is felt and I feel as a society we place more emotional stress on women and expect more from them in roles and pay them less. Physical labour has always been an easier role for me IMO but emotional work is more rewarding and achieves more. If you help people out of their troubles they go out and positively contribute to society through gaining employment.
I prefer physical labour for its lack of mental stress, but I think that there is still this expectation that men will be more capable due to their strength. However, I agree, emotional work can be more rewarding for the positive impacts; even more stressful if you get a negative client/customer, though. Something else that happens more often than it should in the medical industry...
