I guess I am confused by this. Why are you expecting your W to notify the cleaning lady about the laundry?
If you want your laundry cleaned by her - call her yourself and give her that expectation. She's an employee - its none of her business which hamper is in what bedroom. Why on earth would you even consider firing her unless you confirm that she knows she should be doing it?
I get that your wife is not exactly pulling her weight around the house at the moment and that you are frustrated about it. However, you have to deal with the situation that is (and its not going to change until you all are in different households). Tell the cleaning lady yourself that you want your laundry done. Problem solved.
