Earlier quoted context omitted.
your (x times y) work week is a privilege earned by a long history of labour activism in the Western world. With most of "us" being some kind of a software engineer, I'm sincerely curious: was 80-hours workweek ever a mandatory thing for an engineer (teacher, doctor)?
A quick search for “doctor work week” is returning numbers that start around 50 and go up to 108 for an emergency room surgeon. There is a horrible cultural expectation of crazy amounts of overwork in the US hospital world.
Its not great for the doctors, but if you're a patient with an acute problem its much better to have the same few doctors working keeping watch over you than a brand new doctor every 8 hours coming on board that doesn't know anything about why you're there.
