> If you go to most hospitals at 2AM and need a specialist of some kind (say a specific type of surgeon), there’s going to be someone in that specialty on call whose going to get paged to wake up, come in, and see you. Only if you're dying. Come in late Friday and you're going to be sitting in a bed until Monday even if your gall bladder is about to explode.
Sorry, you’re right. Doctors have it way easier than software engineers.
The point was that "on call" is specifically confined as an expectation only to certain types of doctors or under very urgent circumstances.
In addition, doctors have extra special dysfunctions like "too many hours in a shift".
However, many of these are because doctors also have been fighting various efforts to teach more of them which would enable distributing the required extra labor across more people.
