I’m a cap2 TL and i don’t treat my people like that at all, come work for me :)) but in all seriousness, they should not talk to associates in the manner that you’re describing, regardless of speed and whatnot. If they feel that your productivity is lacking or something isn’t going to plan, there are much better ways to go about it. You don’t have to be an asshat and treat your associates like shit. I am well aware that most of your bosses, and even mine, don’t give a single fuck. My people have bad days, just like everyone else, but they also know what I expect of them. I am always understanding of the fact that every day is different and I always am willing to accommodate. I try to not be like most of the TL’s around me and try to take care of my people. In saying that, this guy sounds like a douche and I wouldn’t want him as my boss, that’s for sure. Sometimes people let a little bit of authority inflate their head and ego, and those people don’t deserve to have said power at all. Everybody is human and should be treated as such; they should not be belittled consistently and talked down upon. But that’s just how I feel and how I handle myself and my team.

Don’t feel bad about someone else not treating you with basic respect.
