This Monday, Labor Day is celebrated in the United States, and it is no accident that this country does not join the rest of the world to celebrate its workers on May Day. That, despite the fact that May Day was born in the United States, in the fight for the eight-hour workday that had its epicenter in Chicago in 1886. President Grover Cleveland proclaimed the first Monday of September as Labor Day, in 1894, to separate it from the radical history linked to May Day, a movement led by radical anarchists, socialists and immigrants with very dangerous ideas.
