I use those people that I used to work with as a "what not to do" guide.

Sometimes I want to say to staff "You keep up shit like this and you wont have a job much longer" but I remember how fast people turned on that guy, so instead I have a sit down with them and say "I cant keep not reporting this stuff, its going to risk MY job. So I need you to lift your game because we're friends and all but I'm not going to get fired to protect you and once I start reporting it up the chain, I cant fo anything to protect you"
