Fifty-one workers were killed while they were doing their jobs last year, the Council of Trade Unions says.
Tomorrow is Workers Memorial Day, an international day of remembrance and action for workers who died at the workplace.
The CTU believed Workers Memorial Day was an opportunity for reflection and commitment to change.
"It's all too easy to think of these tragic deaths as just another number; another empty statistic rather than someone loved, someone who was an important part of a community,'' president Helen Kelly said.
"Fathers, sons, mothers, daughters, loved members of family fabric. 11 of the 51 workers who died at work were forestry workers, this makes forestry the most dangerous industry to work in.''
