I was appointed as SUBSTITUTED in Indian Railway [ Eastern Railway] on 10.1.81 followed by permanant on  in the same year. I was again selected directly as commercial clerk through R.R.B /KOLKATA in the year of 1989 via proper channel and I joined in S.E Railway in Adra div. in the grade pay of 2000 in payband 1(6th pay comm.). I was transferred from S.E railway to E.R Railway Asansol division in 1993 at my own request.I got the first promotion in the year 2001 in terms of present six pay commission grade pay rs 2800/ in PB 1. I was again selected for goods guard in the same grade pay in 2005.In the year 2011,I was declared medically de-categorised and my fixation of pay was fixed in the grade pay rs 4200/ in pb 2.now my question is ,"Am i entitled to get MACP benifit after completion of 20 yrs of service"?Had my second fixation of pay {rs 4200} be calculated from 2009 instead of 2011.
another question is from which year my service would be reckoned either '81 or '89??
