I think the common public needs more accountability and efficiency from the govt. servants. Corruption is rampant in many areas and so is inefficiency so it is natural for the tax payers to become angry at such increase. Also such hike is unfair to the honest govt. servants who are resisting corruption, because they get the hike and others known corrupt people get it too.
There has to be a better method of measuring the performance as well as thwarting corruption in govt. machinery.
