The Public Service (Croke Park) Agreement was negotiated and agreed as an Industrial Relations Agreement between public service employers and the public service committee of the Irish Congress of Trade Unions as representatives of employees in the public service. Current discussions in relation to an extension of the Public Service Agreement are being conducted on a similar basis. The Irish Postmasters Union is the representative body for postmasters employed with An Post, which as a commercial semi-state body, is not a party to the Public Service Agreement.
