Well, you better get used to it, because that's just what you're up against.
Like Stinky says, NEVER take any of it personal. Part of their game is hoping you will get mad and lose your cool. Know that ahead of time, and make a vow never to let it happen to you.
For me, that was easier said than done, but you'll learn it. I always had the urge to drive a fist into their face, but I learned to think for a second or two before I spoke, then respond calmly. And they will always be angry if you tell them no, or stand up for yourself.
What you must learn to do, is follow their methods TO THE TEE. In the end, that's all that matters working for these dancing clowns. If they push, push, push you, and you get in a wreck, guess what? The very first thing they will do is start asking you questions about your methods...and if you weren't doing them TO THE TEE, that's how they will fire you. Always follow the methods. That is what will always save you.
A lot of guys here that I respect tremendously, say don't worry about the crap they make us memorize...5 seeing habits, 10 point commentary, all of that. For years, I never knew any of that. Well, where I'm at, the union isn't real strong. And if you get in an accident here, one of the big things that determines how long you're off, and IF you get your job back, is how well you know all of that. So years ago, when I was driving out to my route, I repeated that stuff to myself until I knew it by heart. And now I use it as a moneymaker. Or I used to, anyway, They caught on to me after a while, because they would ask me to come into the office to answer all of those questions. Well, if you know them, let me tell you, you can stretch out those answers for nearly an hour. They don't ask me anymore--unless there is a Ketter audit.
Anyway, I ramble.
Oh yeah, next time your stupervisor tells you that he is "tired of this 9.5 crap", calmly tell him, "yeah, that's funny, so am I."
