Some people are just workaholics and need interventions to actually take a proper holiday.
Personally I’m sure I’d forget to sign out of something.
The only people who should suffer this much are the true busines owners.
Real engineers think about handling things when stuff goes wrong, not "everything will be on the happy path forever".
Yes, there are constraints, but to me this sounds like an unacceptable level of exposure.
My manager doesn't stop overworking. When told on peer performance review that we have people who are consistently overwork because they are swamped, he played it down.
But hey, at least he doesn't encourage overworking either.
