History
In 1984, April 28th was established as a Day of Mourning by the Canadian Labour Congress. This was a day to “mourn for the dead and fight for the living.” In 1991, the Canadian federal government passed legislation marking April 28th as a national “Day of Mourning for Persons Killed or Injured in the Workplace”. This has since become an international movement. The International Labour Organization celebrates the World Day for Safety and Health at Work on April 28th to “promote the prevention of occupational accidents and diseases globally.”
This April 28th, please take a moment to remember those injured, killed, or afflicted with an occupational disease while on the job.
