The Aviation and Transportation Security Act, or ATSA, gave TSA sweeping authorities to, among other things, create its own employee classification system rather than adhere to the Office of Personnel Management system like the vast majority of other Federal agencies. At the time, Congress determined it was best to align TSA with the Federal Aviation Administration, which also has its own employee classification system separate and apart from OPM. Today TSA has 20 percent more employees than FAA and we continue to see significant challenges with the size and scope of TSA's workforce-challenges that are likely exacerbated by TSA's exemption from the OPM system.
