I hate my maid. I really can't stand her. She is always on her handphone and like to talk back to me. She will reply things like, sorry but this is not my job (i had a headache and ask her to massage my head), then during off day she refuse to help look after baby when she is back from her off day. she is Filipino. How to train her to behave herself?

She is not obliged to massage for you in the first place thus I don't think it's fair to say she's not doing her job based on this request. The best solution is to lay down your rules to her so that there can be a mutual agreement like the time she can use her phone and her off day timing (eg it's 8am to 8pm and after which she needs to resume her duties) If she does not accept it then it will be best to change a maid instead of trying to train her.
