Congress has adopted the ETUC (European Trade Union Confederation) slogan for this year's International Workers' Memorial Day which is "Workplace health and safety - it's your right".
There will be a commemorative wreath-laying event to remember all those who have been killed, injured, or made ill at work. The event is also to highlight safety in the workplace.
An online event and ceremony will be broadcast on social media at noon on Wednesday, April 28th.
The Irish Congress of Trade Unions has taken the lead for many years, with support since 2015, from the HSA, Ibec, CIF, and the Government, in marking Worker's Memorial Day.
