I have a serious problem when people come to work sick with a cold, the flu, or bronchitis(sp) and wait till they get near my desk and start either caughing or hacking!
I hate it when people see my light on my phone lit, but manage to call anyway and keep calling until I pick up and WANT NOTHING or people will see me on the phone with a customer and just stand there until I get off and still WANT NOTHING OR SAY ANYTHING IMPORTANT!
Some co-workers instead of having the nerve to ask you to do something, they will drop all these hints out loud to other co-workers.
Or co-workers who have a question, but they have to be all up on you while asking it!
Or those who complain about what they are gonna do, what aint right about the company, how they wish the supervisor would right or say this and that to them and how they will do whatever if they do AND when the time comes they sit there looking stupid!
