The Irish Congress of Trade Unions (ICTU) will release an anti-racism video tomorrow to mark International Workers' Day.
ICTU said that the video is part of an overall plan by unions to counter the far-right and to promote the fact that the trade union movement was built on the simple idea of uniting working people.
ICTU said it has developed a strategy, in conjunction with its affiliate unions, to educate and inform union members and to equip them to oppose hate-filled messages of racism, misogyny and bigotry.
The plan includes a range of measures focussed on combatting the far-right, building workplace integration and seeking to develop workplace leaders of minority ethnic backgrounds.
"Trade unions believe in solidarity, decent work, and social justice for all working people no matter what their background and we will always be there to stand up against those seeking to divide us," said ICTU General Secretary Owen Reidy
"Most recently, this has included stirring up hate, fear, and anger by blaming migrants and minorities for our housing crisis and our stretched public services."
"There are serious issues to be tackled by all of us, including the Government, and these will not be solved by laying the blame on migrants and refugees, many of whom are fleeing war, famine, and oppression," Mr Reidy said.
The two-minute video will be released on social media channels tomorrow to coincide with the Dublin May Day Parade.
Meanwhile, ahead of May Day, the new Irish Secretary of the Unite trade union, has warned that employers must pay for industrial peace.
"Where possible, cost-of-living pay increases will be secured through negotiation – but Unite members will not shy away from taking strike action where necessary," Unite's Regional Secretary for Ireland Susan Fitzgerald said.
"Experience has taught us that the more strike-ready workers are, the more talk-ready employers are," Ms Fitzgerald added.
