No one told them nothing: they just know/learnt what happens if they don't.
One example is very much clear: whenever I say something, there'll be some reaction like:
"you have nothing to complain about" which is close to shut up, and other reactions that are waaay worse.
it's like: you got your rights, now go to work. there is nothing to do anymore.
There won't be one single time that breaking one of those "guidelines" won't have an unpleasant consequence.
We impose that on ourselves? Partially.
