I migrated abroad after getting noc and later i send medical papers for further leave ,now I am without pay and leave.Department is issuing enquiry against me in this matter. I want to get voluntary retirement/resign from TGT post in govt.school. C an you suggest me how this can be possible with maximum benefits and less tension. I am a single parent and my child is studying abroad so I am here with him.
