The workers rose against up to 15 hours work and demanded paid leaves, proper wages and breaks for the workforce. May 1 is observed as International Labour Day in several countries to commemorate the labour movement which ushered in various reforms such as capping the work hours at eight and paid leaves. Labour Day has its origins in the labour union movement in the United States. The first of May is a national, public holiday in many countries across the world, also known as “International Workers Day” or a similar name. Some countries celebrate a Labour Day on other dates significant to them, such as the United States and Canada, which celebrate Labor Day on the first Monday of September.
