I am a 5 year UPS preloader This past week a 3 year preloader suddenly forgot how to load package cars. At least that is what he told management after he got moved from the set of trucks he was loading. He was moved because he couldnt keep his mouth shut and missed too many packages. My part-time sup decided to put him next to me and now I gotta deal with his mouth and his missed packages. The packages he doesnt miss he stacks out behind his cars. He told me he was going to start working even slower because he was they moved him. The part-time sup is now on this guy like flies on you know what. Everyone on the belt just hates the guy. I asked my sup the following: How does this guy get to keep his job with all of the trouble he is causing? His answer was verbatim 1) We terminate him 2) He files a grievance 3) He keeps his job Over and Over and Over Again WHY WHY WHY is this allowed.
