At first the new maid will come on 1/1, so I give my old maid one month notice letter on 12/1, however, the agent said new maide will be postoned and arrive on 2/1. I wonder if the original one month notice letter still valid or I need to give her another one month notice on 1/1? Actually, I don't want to give her second letter...... Anyone can help to answer??? Thanks alot......
