I have a co-worker that irritates my soul! He was out yesterday because he cut his leg with a chainsaw last week and stitched himself up with household needle & thread and that caused him to develop a cellulitis infection. Yesterday was peaceful but I went home ill. Today he's back and annoying me. He's not even supposed to be here. He says the E.R. docs told him to stay off his leg but he can't afford to miss a paycheck. Work is slow so I'm sorting bad parts from really bad parts. He asked to help (his hand is in a cast from a previous accident so he can't work a machine). I reluctantly said "OK". He promised not to talk non-stop then talked constantly anyway about his infection, rearranged my work space so that "we could both access the parts", turned on the overhead exhaust fan because he was hot, then after sorting 5-6 parts, he left! He hopped on his scooter and took off for 20 minutes! He does this all the time! It's like he sees that I'm in a peaceful place work wise and mentally and he just needs to disrupt it! I've complained to our boss but it does no good. Now that my peace and tranquility have been disrupted he's back, off talking to other co-workers while moving tables/chairs and sweeping/mopping the floors.
