"Attempting to negate [TSA workers'] legally binding collective bargaining agreement now makes zero sense – it will only reduce morale and hamper the workforce," said Rep. Bennie G. Thompson, a Democrat from Mississippi and ranking member of the Committee on Homeland Security, in a statement on Friday.

The Department of Homeland Security has revoked the collective bargaining agreement for thousands of TSA employees, a move critics argue will undermine worker rights and aviation security.

A union representing Transportation Security Administration workers calls the Department of Homeland Security's decision to end the collective bargaining agreement with them an “unprovoked attack.”
