can deduct her salary if not more than 4 consecutive sick leave granted by doctor and if she has not earnt enough sick leave (2 days for working 1 full month for the first year).
consider making use of the cam record to terminate her immediately for the reason of neligence in taking care of BBs (leaving BBs unattended and watching TV) and pretending to be sick.
See if you can ask for the medical report from hospital so that you will know more about the doctor's comment on her condition (need the maid's consent, you can tell her that it is for claiming insurance).
