The story
Talks on forming the new union were sparked by a 2011 report of the commission on the Trade Union Movement, which was set up by the Irish Congress of Trade Unions to look at the way public service unions were organised. There were 19 unions operating across the public sector at the time. The commission recommended that unions affiliated to the ICTU that were working in common areas should collaborate more closely and explore possible mergers, so they could serve their members better and have more impact.
