I'll admit to enjoying one! A Saudi trainee who told me to my face that I couldn't do it.
I had to recommend not keeping a guy who was on a 30 day trial from a temp agency.
We gave him the easiest deflashing job in the shop. Rate was 60 an hour, but you could easily do 80 with out sweating. He was barely getting 40 an hour after 15 days. Every time I walked into his area he had his feet up and was ambling through a piece.
Another time I was supervising a crew that was monitoring an asbestos abatement. You walk in get the names from the foreman, set up your equipment and leave. I walk in and he is threatening one of the abatement contractors crew. Some one he should not even be talking to. Went back to the shop and told the shop manager to handle it. He got fired over the phone and told to pick up his stuff on the weekend. He could have cost us about 100k.
