I'm working in an organization since 2011. My ESIC contribution was deducted from my salary from 2011 to 2013. After July 2013, my salary became more than 15k, so the ESIC contribution was not deducted. From January 2017, I was again under ESIC, and my contribution for the same was deducted until March 15, 2017, as I had to go for maternity leave from March 16. Now I have joined back, and I went to my ESIC office to claim salary for the past 6 months. However, they refused, stating that I should have contributed for at least 9 months to claim maternity benefits. Please advise.
