Reformers in the United Auto Workers won day-one strike pay at the union’s constitutional convention in Detroit last week. They also forced open debate on the top concession that has weakened the union in the last fifteen years — tiered contracts that condemn newer workers to lower pay and benefits beside “legacy” workers doing the same job.

This was the first UAW convention since a leadership corruption scandal erupted, reformers won a member referendum last fall to adopt one-member-one-vote for top officers, and the auto industry began a serious transition to electric vehicles. Held every four years, the meeting has usually been a stale coronation of leaders. A newly organized reform movement turned the convention into a rowdy debate that, for moments, even overruled the top union leaders.

Again and again, members of the Unite All Workers for Democracy reform caucus (UAWD) and other delegates gathered the numbers to put their issues on the convention floor (that is, in between endless speeches from politicians, glowing videos about top union officers, and other time-wasting snoozes).
