As far as a coworker getting mad at me it was probably because I felt the need to discipline them in some way but I usually like that person and I explain to them what I'm doing is not because I don't like them it's because I have a job to do and it's something they need to hear. I feel like the co-workers that I've had to discipline and have conversations with the most ended up appreciating me more. I've had several of them when they've moved on to their careers tell me how much they respected the fact that I gave them a good worth ethic.
