     ¹[(4) On receipt of the notice, the employer shall permit such woman to absent herself from the establishment during the period for which she receives the maternity benefit.]
     (5) The amount of maternity benefit for the period preceding the date of her expected delivery shall be paid in advance by the employer to the woman on production of such proof as may be prescribed that the woman is pregnant, and the amount due for the subsequent period shall be paid by the employer to the woman within forty-eight hours of production of such proof as may be prescribed that the woman has been delivered of a child.
     (6) The failure to give notice under this section shall not disentitle a woman to maternity benefit or any other amount under this Act if she is otherwise entitled to such benefit or amount and in any such case an Inspector may either of his own motion or on an application made to him by the woman, order the payment of such benefit or amount within such period as may be specified in the order.
