Sir, I don’t think it is necessary. You have already got your health scheme card, I hope. While claiming reimbursement, the card itself is the record of your enrollment.
It should be extended by govt. but spell should be minimum 90 days so that teachers in leave vacancy may be appointed by school … my personal feelings. and i don’t know whether Govt. will provide similar facility to teachers or not. (e.g. Child Adoption Leave).
