I am a private sector employee, planning to resign after my 10 months of service. My mother is receiving treatment at an ESI outlet and may require surgery soon. I am going abroad in a few months. How long can I continue to use my ESI benefits? Will my presence or signature be needed for the treatment and reimbursement of lab tests? My sister has recently started working and has an ESI account. Is it possible for my mother to receive benefits from her account after my resignation?
