May 1st is an internationally recognized holiday of sorts for communists and socialists. More than 600 organizations, including self-identified communist and Maoist groups, have organized 3,000 events and demonstrations across the country today for what is essentially a nationwide general strike. Their slogan is “No Work, No School, No Shopping.” Both major teachers’ unions—the National Education Association and the American Federation of Teachers—are active participants and promoters of this May Day mayhem.
