The United Nations began celebrating International Women’s Day (IWD) on 8 March during International Women’s Year 1975. However, the first National Woman's Day was observed in the United States on February 28, 1909. The Socialist Party of America designated this day in honour of the 1908 garment workers' strike in New York, where women protested against working conditions.
International Women’s Day has assumed a global dimension for women in developed and developing countries alike. The growing international women’s movement, which has been strengthened by four global United Nations women’s conferences, has helped make the commemoration a rallying point to build support for women’s rights and participation in the political and economic areas.
For 35 years, the IRSST has been interested in health and safety of women in the labor market and the gender difference.
