International Workers’ Day (also known as May Day) is a celebration of the international labour movement and left-wing movements. It commonly sees organized street demonstrations and marches by working people and their labour unions throughout most of the world. May 1 is a national holiday in more than 80 countries. It is also celebrated unofficially in many other countries.
International Workers’ Day is the commemoration of the 1886 Haymarket Massacre in Chicago, which occurred after an unknown person threw a dynamite bomb at police as they dispersed a public assembly during a general strike for the eight-hour workday. In response, the Chicago police fired on the workers killing dozens of demonstrators and several of their own officers. May Day was formally recognized as an annual event in 1891.
Happy International Workers’ Day.
