♦ May day is commemorated to celebrate the global labor community and to commemorate their contributions and the historic hay market riots of 1886.
♦ The origin of International Labor Day can be traced back to the labor union movement in the United States in the 19th century.
♦ Previously, workers were forced to work 15 hours a day. On May 1, 1886, there was a strike in Chicago, calling it the Haymarket riot because the working hours were 8 hours.
♦ On May 1, 1923, the Labor Kisan Party of Hindustan celebrated International Labor Day for the first time in Madras (now known as Chennai), India. It was also on that day that India was used with a red flag.
