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.”

DHS said that a “select few poor performers” had been taking advantage of the agreement’s family and sick leave policy. DHS’s press release also claimed that nearly 200 officers, out of TSA’s screening workforce of approximately 47,000, work “full time” on union matters.

The Department of Homeland Security says it's ending the collective bargaining agreement with the tens of thousands of frontline employees at the Transportation Security Administration responsible for protecting air travel.
