I think many do not know or skipping the fact that the central govt. employees were getting 50% Dearness Pay(DP) prior to this recommendation which was granted during the NDA Govt.
Now the 6th pay commission has recommended a increase of about 40-50% on basic. This amounts to no effective increase in perks.
However, due to the grade pay and other minor increases recommended for transport allowance and other such minor things, the effective increase iis only about 10 -15 % only.
