1. Sir, it would be better if you clearly indicate what your doubts are and what type of benefits you are seeking.
2. From your above remarks, it appears that you want to know about the contribution period and benefit period as per the ESIC procedure. In this connection, I request you to please refer to Regulation 4 of the ESI General Regulations, 1950, which is self-explanatory.
3. I would like to further inform you that under the ESI Act, 1948, and the rules/regulations framed thereunder, Medical Benefits, as well as Temporary Disablement/Permanent Disablement (or dependent benefit in case of death) due to employment injuries, start immediately from the date the person becomes an "employee" under the said Act.
4. If you have any doubts, I suggest visiting your appropriate Branch Office of ESIC and seeking guidance about your eligibility for various benefits under the said Act. Please ensure that you have your Pehchan Card issued by ESIC when you visit the said Office.
Regards
