A federal judge in Seattle has thrown a legal wrench into Homeland Security Secretary Kristi Noem’s plans to blow up a union contract that protects Transportation Safety Administration (TSA) workers, saying she “afforded no notice or process” for staffers before “simply shredding the contractual promises” in a ruling this week.

U.S. District Judge Marsha Pechman granted a preliminary injunction on Monday, siding with members of the American Federation of Government Employees, who are suing Noem and the Trump administration over its rescission of a seven-year collective bargaining agreement that the government signed off on last year.

The AFGE members requested injunctive relief to preserve that agreement after Noem issued a memo on Feb. 27 to cancel it within 90 days and terminate all pending grievances filed by the AFGE on behalf of TSA employees.

“AFGE has demonstrated a strong likelihood that the Noem Determination constitutes impermissible retaliation against it for its unwillingness to acquiesce to the Trump Administration’s assault on federal workers,” wrote Pechman, a Bill Clinton appointee, in a 41-page ruling.

“AFGE has shown the Noem Determination likely violates Due Process, having afforded no notice or process for AFGE and its members to work with DHS and TSA to resolve any disagreement before simply shredding the contractual promises of the CBA,” she said. “And AFGE has shown it is likely to succeed in showing the Noem Determination is arbitrary and capricious in violation of the Administrative Procedure Act, particularly given its complete disregard for the 2024 CBA and its mischaracterization of AFGE’s role.”

Pechman said AFGE’s lawyers “convincingly” argued that Noem’s directive violates the First and Fifth Amendments, along with having alleged ulterior motives.

“The Noem Determination appears to have been undertaken to punish AFGE and its members because AFGE has chosen to push back against the Trump Administration’s attacks to federal employment in the courts,” Pechman charged.

“The First Amendment protects against retaliation for engaging in litigation and public criticism of the government,” she said. “And the Noem Determination’s threadbare justification for termination of the CBA exposes the retaliatory nature of the decision.”

In its motion for the preliminary injunction, AFGE’s lawyers said Noem’s memorandum was “directly attacking AFGE” by name, contending that determinations on bargaining rights were “misplaced directives” that have “solely benefited” AFGE at the “expense” of transportation security officers (TSOs).

“This targeted attack on AFGE came on the heels of AFGE’s public efforts to push back against the Trump Administration’s attacks on federal workers,” the motion said. “It is apparent, moreover, that the administration is both tracking and fixated on those who seek to enforce their rights in court.”
