I work with a complete dim wit (being nice about that description!) and she has been working the same amount of time as me. If I call in sick which is NEVER, guaranteed I get a phone call before 9am. I was thrown into my job and had to work things out for myself, and she was the same, but I have had to train her because she has no idea. When I go on mat leave, I am considering changing my mobile number so I don't get stupid questions! Thank the Lord she doesn't realise I have a home phone!
