I'm still at university, so despite my previous post having a bit of accusatory tone, I was genuinely curious. At least my profs told us many times that we should be prepare that stress at work is absolutely normal and that if we can't handle it, just drop out.

In my experience, being a workplace or even academia, there's as many types of work environments as types of teachers.

In the end, management (or founders if it's a startup) set the tone and who they end up hiring (thus, who will manage your work). And management is just normal people in the end.

Working minimum wage jobs of most stripes or in the service industry (retail, restaurants, that sort of thing) is far more stressful in my experience. Working conditions tend to be worse and people treat you worse. Not that tech isn't stressful at times, just that I've never felt like I needed to go to the walk-in to cry about it.
