The US Department of Homeland Security is proceeding with plans to terminate the collective bargaining agreement covering Transportation Security Administration (TSA) officers, despite a federal court order blocking an earlier attempt. The decision sets up a new legal battle over collective bargaining rights for front-line airport screeners at a time when Congress is trying to restore broader protections for federal workers. DHS Secretary Kristi Noem justified the change in a September 2025 determination, citing compatibility issues with national security and arguing that union administration imposes ‘wasteful’ costs. The American Federation of Government Employees (AFGE) calls the decision illegal retaliation and vows to challenge it in court.
