President Michael D Higgins will lead the centenary commemoration of the 1913 Lockout later today.
Up to 80,000 people are expected to attend the event - which will be mostly focused around the Larkin statue on O’Connell Street, in Dublin.
It gets underway at 12.30 and Dublin City Council are emphasising that the city centre will remain open for business.
Sallyann Kinahan, the Assistant General Secretary of the Irish Congress of Trade Unions said the implications of the Lockout are still evident today:
"We shouldn't forget the struggle that took place 100 years ago that helped in terms of the formation of institutions in this state that have improved a lot for working people," she said.
"But I should also add to that there is a lot more to be done."
