Celebrated on 04/28/2026
Workers' Memorial Day, observed on April 28, was inspired by the 1970 Occupational Safety and Health Act in the US, but Canada actually started it earlier in 1984. The date is significant because it marks the anniversary of the Occupational Safety and Health Act's passage in the US and the day when the OSHA was enacted in 1971.
Workers' Memorial Day was first proposed by the Canadian Union of Public Employees (CUPE) in 1984, and the first official observance took place on April 28, 1985, in Canada. The date was chosen to commemorate the anniversary of the 1914 Workers' Compensation Act in Ontario, which was a landmark in workers' rights. In the United States, the day gained traction after the AFL-CIO declared April 28 as Workers' Memorial Day in 1989, and it was officially recognized by the US Congress in 1990 with a resolution calling for national observance.
Over time, Workers' Memorial Day has evolved from a union-led event to a globally recognized day of remembrance. In many countries, it is marked by ceremonies, vigils, and workplace safety campaigns. The day is used to honor workers who have died or been injured on the job, and to renew commitments to improving workplace safety. Modern observances often include moments of silence, laying of wreaths, and educational events about occupational health and safety standards.
