Employees in high-level pay systems have complained for years about the pay compression effect of the salary caps, but so far have not succeeded in getting relief from the current arrangement. By numbers, the largest group of employees affected by the cap consists of senior executive service members: the top three of the six SES grades in all localities now are up against the cap, and in certain localities the second and third grade are up against it, as well. In many cases those executives are making not much more than employees they supervise who are in the upper reaches of the general schedule. The cap also applies to the top two of the eight administrative law judge rates in almost all localities and limits pay of some employees in senior level and senior scientific or professional positions, too.
