I am working wit ONGC with Basic Pay of Rs. 24,900. Before joining ONGC , I was working with NTPC Ltd. with Basic Pay of Rs. 29,980. I joined ONGC at a lower Post through Open Written Competition & Interview. I had submitted the NOC at the time of Joining. My scale at NTPC was 29100-3%-55,500. However, I joined ONGC in a Pay scale of 24,900-3%- 50,500. Please confirm , whether my Basic Pay of NTPC would be protected at ONGC. Both the Organizations are PSUs.
