Until about the 5th CPC, there was no major change in the increment system. But, the 6th CPC brought in landmark reforms in the increment system.
Until then, increments were given in the form of a consolidated amount. The 6th CPC recommended that it be calculated on percentage basis. The Central Government ordered that it be calculated at 3% of the employee’s basic pay with effect from 1.1.2006.
The CG employees didn’t realize how useful this was going to be. They thought it wouldn’t amount for much. It was Rs.75 for Rs. 3050 and revised to Rs. 210 for Rs.7000 with simple calculation.
