Trinity College Dublin (TCD) has been accused of breaking the Croke Park Agreement after refusing to implement a Labour Court recommendation to reinstate three staff made redundant last year.
The Irish Federation of University Teachers (IFUT) general secretary, Mike Jennings, said the court's decision was binding and accused the college of reneging on the deal.
IFUT is now referring the matter to the National Implementation Body for the Public Service Agreement, which polices the deal. He said a meeting of the IFTU national executive tomorrow would consider the possibility of the union balloting to leave Croke Park.
The three staff had been employed on contracts of indefinite duration -- effectively permanent status -- and were told that their jobs were linked to the availability of funding.
The college said it had a well-established practice of effecting redundancies where the supporting funding ceased.
