I've been at my current job a year. Very much proven myself. No callouts, I'm always early. I am always down to work late and help out my coworkers on their routes. The other day I was having some tummy trouble and simply told my manager I was going to bang out my work and head out early because I wasn't feeling too hot, without giving any details. He was giving me a bunch of friction. I understand that he deals with bullshit all the time. But I am not the guy. One of your best tells you he needs to knock off a little early, after finishing his work for the day, you should say alright man have a good one! Anyway I told him I'd really prefer to go home and blow up my own toilet if it was all the same to him. Apparently that was enough.
