You ask the question “AIBU to think that I can work a 60 hr working week and still hold the family together?”
In my opinion, you can work the 60 hrs but it won’t be YOU holding the family together. It will be whoever is doing the brunt of the childcare, the household chores and admin, cooking the nutritious family meals (rather than chucking in a pizza or ready meal because that’s all you have time for, making sure that DC keep up friendships and develop relationships with extended family, helps them with homework, makes the medical appointments and arranged hair cuts, takes them to get new shoes when they’ve outgrown theirs, takes them to swimming lessons, go to school events, sort out any problems the children have be it discussing their friendship problems or communicating with school to iron out issues with them. You can’t do all that if you are working so many hours.
A few people have said on here “well plenty of men do those hours.” Yes, they do but that’s usually because someone else is doing all that stuff at home. (Could be a partner, could be a grandparent, could be a brilliant nanny)
But my point is, THEY are “holding the family” together because if they didn’t do all those things, they wouldn’t get done. Because YOU wouldn’t be available to. It’s as simple as that.
DH worked those sorts of hours when our kids were younger. I worked PT so I could do all those family tasks that needed doing. Now we’re both full time but I work a standard 37 hrs a week and that’s enough! The kids are older so easier in some ways but I am older too (44) and my energy isn’t what it was 10 years ago. I have an elderly parent too whose health is becoming a concern. Working full time doesn’t necesariky get easier as your children get older, there are just other issues that become apparent that weren’t there before. I’m actually looking to going back to part time as Life was so much more enjoyable for ALL of us when I was.
