Workers' Memorial Day 2027

What is Workers' Memorial Day?

Workers' Memorial Day is held every year on April 28 to remember workers who have died, been injured or become ill because of their work. In the United States it is promoted by the AFL-CIO and marks the anniversary of the date the Occupational Safety and Health Act took effect in 1971. Internationally, April 28 is also the International Labour Organization's World Day for Safety and Health at Work.

Why it matters for workplaces

Behind every serious incident statistic is a person, a family and a crew. Workers' Memorial Day is a chance to pause, remember, and make sure the lessons from past incidents are still being acted on.

Ways to take part

1. Hold a moment of silence. Pause work at a set time to remember colleagues and workers everywhere.
2. Share lessons learned. Talk through a past serious incident, what caused it and what changed afterward.
3. Check that fixes stuck. Review the corrective actions from past serious incidents and confirm they are still in place.
4. Strengthen your investigations. Make sure your incident investigation process looks for root causes, not blame.
5. Join a local event. Many unions, safety councils and communities hold memorial events on April 28.
