This bill brings Transportation Security Administration employees under the federal personnel system established by Title 5 of the U.S. Code, replacing the TSA's current separate personnel management system. The change would apply to all TSA employees, with a conversion deadline of December 31, 2024, and would grant TSA workers standard federal employee protections including collective bargaining rights, grievance procedures, and access to federal retirement and leave benefits. The bill includes safeguards to ensure no current employee experiences a pay reduction during the transition and requires the Office of Personnel Management to establish new position classifications and pay systems for TSA roles. The legislation also directs the Government Accountability Office to review TSA recruitment, promotion practices, diversity in leadership, and workplace safety policies, while requiring the TSA to study whether screening agents' commute time to parking areas could be counted as work hours and to report on assaults against employees.
