Under a separate pay-setting formula, raises for members of Congress and certain top executive branch and judicial officials are linked to an employment cost index using a different measuring period. For 2008, the pertinent figure is 2.7 percent. The House in voting on its version of the general government spending bill turned back an attempt to deny the raises. Those rates, in particular the executive schedule pay scale for top political appointees, are used to set pay caps for many high-level senior career personnel systems, most numerously in the SES. However, SES members no longer get pay raises automatically but rather are under a pay-for-performance system in which their pay is set within certain ranges under the applicable caps. Also, the rate for Congress, federal judges and top executive officials might be set lower, since by law their raises can’t exceed the across-the-board component of the general schedule raise.
