About Workers Memorial Day
Workers Memorial Day is observed on 28 April to remember workers who have died, been injured or become ill because of work and to reinforce the importance of preventing occupational harm.
The International Labour Organization records that 28 April has been associated with the international trade union movement’s Workers Memorial Day commemoration since 1996.
Why Workers Memorial Day matters
The day combines remembrance with prevention. It honours workers and families affected by occupational injury and disease while drawing attention to the systems, standards and practices that can make work safer.
Because the observance deals with death, injury and illness, respectful commemoration matters. Practical safety learning and evidence-based prevention are more useful than sensational descriptions of workplace tragedies.
History of Workers Memorial Day
Since 1996, 28 April has been associated with the international trade union movement’s commemoration of victims of occupational accidents and diseases as Workers Memorial Day.
The ILO became involved with 28 April activities in 2001.
In 2003, the ILO designated its World Day for Safety and Health at Work as an official global campaign on the same date. The ILO describes that programme as recognizing both commemoration and prevention; it does not erase the distinct trade-union Workers Memorial Day identity.
