I can not stand it when you're at a toxic workplace, have been there forever, and have been put through an endless amount of bullshit since day one. Then, someone else who has always been favored and had it 100X easier and is paid more begins complaining to you about the most trivial things and how they're tired of being there. When they have no idea what you and the rest of the people have been going through since starting, and act like people being mistreated is some new thing. Meanwhile these people have dragged their feet and acted like the weight of the world was on them and only them since day one, and were too self-centered to ever notice how anyone else was treated.
I also can't stand the people who try to get others to leave by being like “Hey. I've seen some shit man” and want you to tell them gossip because they don't have any of their own about why where they're at is a shit place to work.
