The Civil and Public Service Union has rejected claims they are refusing to facilitate changes, which would clear the backlog in applications for social welfare benefits.
Speaking on RTÉ Radio, Minister for Social and Family Affairs Mary Hanafin said one issue was that in a pilot scheme in Dundalk the union wanted promotion for every member dealing with new claims.
However assistant general secretary of the CPSU Derek Mullen said the union was willing to cooperate and had offered to hold negotiations on the issue.
