Last year a network of unions and community organizations organized the largest May Day actions in U.S. history: 1,200 actions in all 50 states. This year, the stakes are even higher, and the examples inspiring us are even bolder. The Chicago Teachers Union’s House of Delegates, the union’s governing body, has endorsed a national call for “no school, no work, no shopping” on May 1. Recent boycotts of Disney, Target, and Tesla have shown us that we can shake the pillars of corporate America.
