I started a new company about 8 months ago, and was given an Apprentice who started 9 months ago.
About 1 month ago, after reprimanding this guy (Sideshow Bob) for his lack of attention to detail in his make-up, and protection of finish, I get the I've been here longer than you diatribe.... Several new holes ripped in the proccess of letting him know I was his direct supervisor, (something he never quite got) and an education on how quick I can go from democratic to autocratic leadership, and the fact I have been in this trade 16 years longer than him just stopped that dead.
Last week he tells me he has learned so much from me.... I ask, like what? "Never question your judgement." He says. I say, "No, never not question my judgement - just never question my authority." Oh.....
Anyway, my point is that, even on equal standing rank to rank, etc, sometimes you need to draw a line in the sand, so to speak. The good news is that he wont come bragging about the garbage work he does until he's sure he can....
