The union representing lower-paid civil servants is warning the Government it will launch a number of equal pay claims which could cost the State up to €300m in back-pay.
The CPSU aims to close the gender pay gap in the civil service.
The union says the first case will centre on clerical workers earning €10,000 less than prison officers for doing the same work.
General Secretary of the CPSU Blair Horan is confident they will succeed, especially on the back of the recent Garda equal pay case, saying: “We’re now going to extend that claim, throughout the civil service and other government departments and we believe we’ve a good chance of success.”
