A person joined in the post of LDC (Die in Harness Case) with PB 6240, GP 2600, DA 8840, HRA 1326, MA 300, on Dec 2017. He was denied IR then, as his appoinment letter states temporarily appointed (as usually. written in all appoinment letters). Was he entitled for the IR at that time? Kindly please advise me in this regard.
