Although it's not in the contract, do you give your helper off days on both Hari Raya Puasa and Hari Raya Haji, on top of her usual off day? Do you also give red/green packet and how much do you give?

I would say then it depends greatly on how comfortable you are with giving her the off days. It could be anything as simple as even stay home, rest day if you feel that more should be given to her then maybe let her go out. As for the red packets, there is no amount to it. The sincerity is more then enough. It all depends oends on how much you can afford.
