In her letter, Collins wrote that while the White House budget calls for the personnel flexibilities recently granted to the Departments of Homeland Security and Defense to be extended government-wide, “the committee believes it is prudent to evaluate implementation of the system at the Department of Homeland Security and subsequently the Department of Defense, for which implementing regulations were just recently published in proposed form, before considering extension of the administration’s proposal in earnest.” Similarly, Lieberman wrote that “now that DHS and DoD are undertaking an experimental revamping of the civil service system, we should at least wait to see how it works before we consider extending such power to other agencies that do not have critical national security responsibilities.” He wrote that the rules at those departments “may undermine key employee protections that prevent workplace abuses and improve employee performance.”
