The First of May is commemorated around the world as International Workers Day or May Day. Its origins lay in the Haymarket Massacre, an infamous act of state repression designed to bludgeon the burgeoning US workers’ movement. Instead of defeating the workers’ movement and its demand for a more just world, it sparked international solidarity. Today, throughout the United States and the world, workers, including at Amazon, Target, and Whole Foods, are continuing to fight for their basic rights as workers. Their collective action aimed at building a more just world represents the power and importance of free speech and the right to protest.
