I think some people just assume that salary revisions is up to MOE HR to decide. It is guided by principles that are similar across all ministries as PSD has the final say, especially since the money still comes from the taxpayers money.

Those pple who complain should really understand how the MX scheme revision has been. It is similar that the lower subgrades and higher subgrades have a larger increment.

The likely explanation is higher attrition at both the lower and upper subgrades, as pay increments at public service level has to be backed by statistics and numbers. Not some conspiracy theory that the top decides to pay themselves more money.
