My DS and his husband work every hour under the sun. DS is in the office 8am-10pm very regularly and dsil works fewer hours but still a heck of a lot.
They've both done very well for themselves academically, allowing them to reach their current jobs. DS works in Law, and together they have a gross salary of c£200k
Wow you might think, a huge amount of money. This is London, and so their small 2 bed flat has a mortgage of £800k on it, and so most of their salary goes on keeping a roof over their heads (as do most peoples).
They have no time whatsoever, and often work 6 or 7 days a week, long long hours. Yes they can afford nice things, but the cost of living in London is so high that it's negligible.
AIBU to think working this hard is not healthy, nor worth it.
If I think to dh and I, our situation is work 35 hours each a week, a decent house, no fancy things, but a nice life.
