As per maternity act there is no such rule for women employee,like she has to complete 90 days of 180 days ,she is entitle to receive every benefit from employer .just she has to serve a notice to employer, As per law-
"Any woman employed in an establishment and entitled to maternity benefit under the provisions of this Act may give notice in writing in such form as may be prescribed, to her employer, stating that her maternity benefit and any other amount to which she may be entitled under this Act may be paid to her or to such person as she may nominate in the notice and that she will not work in any establishment during the period for which she receives maternity benefit.
So i think now employer should not deny to give you leave benefit under this Act.
you can take a legal advice also.
