Yeah f that

No idea. Here in the 🇺🇸 nurses work 12 hr shifts, but I’m not sure about others. I’m sure when doctors are first starting out (residents) they can/must work extremely long shifts. I believe fire emergency personnel also work extremely long shifts.

Yes but they'll have health problems soon.

I worked in IT at a hospital, I was 2 weeks on call at a time, there were a few times I was on-site for 30ish hours trying to deal with shit (I did get to eat and sneak a nap or two in a closed wing)

I think that's common for medical residents and on-call hospitalists, and maybe other professions idk about

Yes I've done It and I was actually working not just being there and not just sleeping as I had two jobs at the time.

Yes, some people do - I think they take breaks or have people fill in for them. I guess it depends on the type of job you're referring to. Some of the staff in our programs do 24 hour shifts but they have "downtime" during the shift.

People can be 'on call'. Which counts as work in some industries.

Like Kate said, you're not working the whole time. Sometimes just being there counts - even sleeping.

A shift might seem long that way, but there are jobs that do it. 24h shift doesn't mean 24 h steady work. It might mean 10 h work and 12h standby with occasional tasks interrupted by a little rest.
