A surgeon is probably one of the very few jobs where it really would be difficult to be flexible but then again, if the surgeon's wife is also a surgeon, they would still have to find a way of managing things between them. Or they would have to buy in additional support.
A surgeon is just one example of someone in a high earning job with a lot of responsibility, who needs to be on site to do that job. Same goes for any hospital doctor, project manager, pilot, military officer… the list goes on. Many careers are not compatible with raising kids unless you have
a) a partner who is a SAHP or fits their work around the family or
b) childcare in the form of a live in nanny or relative.
To progress in many careers you simply can’t regularly request flexible hours, short notice days off, leave early, take holidays that sync with school etc. To get promoted and be at the top of your game you need to dedicate time to work. Because there are other people keen to get the promotions who don’t have kids, or have kids and a SAHP to cover all the holidays, half terms, inset days, kids being off sick from school etc.
It’s a shame there aren’t more high-earning women. But the brutal reality is each pregnancy sets you back in your career (especially if you want a long mat leave) so it tends to be the man who gets ahead career wise while his wife is caring for the baby.
I know a married couple who are both consultants (different fields but full time). They both love their jobs. They have 2 kids and a nanny, and often talk about how nice it would be to see more of their kids.
