Last weekend, UAW Local 2865 became the first local to call for the expulsion of a police union from the AFL-CIO, insisting in a resolution that the federation kick out the International Union of Police Associations (IUPA). It was a laudable move that evinced a commitment to social movement unionism — other locals should follow suit.

The UAW local, which is comprised of 13,000 teaching assistants and other student workers on University of California campuses, specifically decried cop unions’ lobbying against oversight, support for politicians opposed to police accountability, and dogged defense of officers accused of abuse.

“Historically and contemporarily,” the resolution reads, “police unions serve the interests of police forces as an arm of the state, and not the interests of police as laborers.”
