No. That is not possible. ESIC has rejected your claim because you should not have completed the required contributory condition of 70 days contribution in the 2 contribution period preceding the expected date of delivery. Again your leave is not during the benefit period. However, in respect of an employee who has or cannot get maternity benefit from the ESIC shall get it from the employer if she satisfies the eligibility conditions as per Maternity Benefits Act which says that a woman employee should have 80 days service during 12 months preceding the date of or expected date of delivery. Though I do have doubt regarding the qualifying phrases of "12 months preceding the expected date of delivery", there seems to be no interpretation that one should have worked for 12 months and in that 12 months there should be 80 days working. If so, you are eligible to maternity leave paid by your employer.
