I keep seeing this or similar comments. A reply like this would almost certainly equate for many people to quitting their job on the spot.
I'm puzzled why so many people think everyone has this luxury.
There have been many times in my life where I've had bosses make shitty unfair demands, and while I would have loved to stick it to The Man and thrown off my proletarian chains the reality was I needed the damn job to pay my bills and quitting on the spot was not a sensible option.
These sorts of discussions remind me of times I've hung out with guys who've witness some sort of verbal altercation, with somebody then insisting that if anyone every spoke to them that way they would kick his ass into next week. But we all knew how easy it was to talk like a tough guy when it wasn't your ass on the line.
Yes, if your boss is an asshole then you need to figure out how to get to a better situation. But telling people to take a hike is not everyone's best career move, and having the option to make a bad situation a bit less onerous is a good thing.
Your lack of planning is not my emergency
