May Day is also called International Workers’ Day or Labour Day.
The day celebrates the struggle, dedication and commitment of the working class and is an annual public holiday in several countries.
On 1 May 1886, Chicago and a few other cities of USA were the sites of a major union demonstration in support of the eight-hour workday demand.
In 1889, the International Socialist Conference declared that in commemoration of the Haymarket affair, 1 May would be an international holiday for the labour force (International Workers’ Day).
The first Labour Day in India was hosted by the Labour Kisan Party, started by Singaravelu Chettiar, in Madras in 1923.
