The main purpose of this legislation, known as the Air Traffic Controller Protection Act, is to ensure that any significant reductions in the workforce of the Federal Aviation Administration (FAA) require approval from Congress. This aims to maintain oversight and accountability regarding staffing decisions that could impact air traffic safety and efficiency. Key provisions of the Act include a requirement that if the Secretary of Transportation wants to reduce, replace, or outsource 1 percent or more of the FAA workforce, they must first obtain explicit approval from Congress.
