So my manager just took this position about 6 months ago. When he first started, I was not too kind to him because he came in here super gung-ho that he was going to switch around a couple of processes and I pretty much said, "uhhhh I don't think so, because I'm the one who put in those processes in place"...so right off the bat, he was already stepping on my toes, so to speak. And we even had to get our regional manager involved because I was not gonna deal with this dude. So the regional manager does speak with him, and gave me a raise to stay on and not abruptly quit my job. Since I've gotten the raise I've been pretty chill/easy going. A few days ago, it was just me and the manager at the office so we started talking and he told me how when he first started this job, he had to go to the ER because he was having panic attacks, so I kinda felt bad about that, because I know I was a massive b!tch when he started working here. Him and I are cool/cordial now but at times I feel like he's scared of me, or he's almost like walking on eggshells around me...
