So it makes sense that this year’s call for an Occupy general strike—whatever ends up happening on Tuesday—falls on May 1. May Day is a beautifully American holiday, one created by American workers, crushed by the American government incubated abroad, and returned to the United States by immigrant workers.

The history of May 1 as a workers’ holiday is intimately tied to the generations-long movement for the eight-hour day, to immigrant workers, to police brutality and repression of the labor movement, and to the long tradition of American anarchism.
