Sorry to break this MH circle jerk but number 1 could well be extremely career limiting and work social limiting advice. Work is just that; work, the people aren't there to hold your hand past their basic legal obligations.
Sorry, I know that sounded blunt and youll come back saying about how employers should care more about their employees MH but the truth is that they don't particularly, especially not in low skilled/experienced roles which a majority of the people reading this are going to be in.
