The lady in question has worked for 4 years and she is entitled.
I would suggest to the lady:
You may submit the intimation of pregnancy and expected date of delivery to appointing authority, Chairman with copy of the Doctor’s Certificate Rx showing date of delivery and notice for Payment of Maternity Benefit and stating that your maternity benefit and any other amount to which you are entitled under this Act may be paid to you.
She needs to claim medical bonus also(Rs3500)
In case of any issue,raise level to Labour Commissioner.
