May 1 is Labour Day in Most Countries Except the US and Canada

On 1 May, millions of workers around the world will celebrate International Workers’ Day, also known as Labour Day or May Day, to commemorate the historical struggles and gains made by the labor movement and to promote their rights and interests. The day originates in the 1886 Haymarket affair in Chicago, where workers staged a general strike for the eight-hour workday and faced violent repression from the police. Since then, the day has been adopted by various socialist and communist groups, trade unions, and progressive movements to symbolize workers’ solidarity and resistance.
