Our au pair has been with us for four weeks and it's just not working. She has sole charge of a four-year-old for three days a week while I am at work. I don't feel she has bonded with him at all. She seems to resent doing any housework and does it badly. I don't think she can cook, although she tells me she can. She hardly communicates with us at all. I am going to give her two weeks' notice, but I'm not proposing to pay her for those two weeks because I won't ask her to do any work. Has anyone else had to sack their au pair? I'm really not looking forward to it, but I think it has to be done.
