Trade union Siptu has told the Dublin Airport Authority (DAA) that the "current negotiation process is exhausted" in long-running talks aimed at resolving a pension dispute.
It has told the DAA that it now intends bringing the dispute to the Labour Court "at the very earliest date".
The talks to date have centred on finding a solution to resolve a €700m-plus pension deficit at a scheme that serves about 14,000 former and current staff at the DAA and Aer Lingus.
"We were somewhat surprised to receive this communication from SIPTU and will seek direct contact next week to attempt to ascertain under what areas they wish to refer the ongoing pension talks to the Labour Court," said a spokesman for the DAA .
Up to now, talks with the DAA had been considered by Siptu to be more progressive than those with Aer Lingus.
The union had already served – and then withdrawn – notice on industrial action on Aer Lingus over the pension deficit.
The DAA has told Siptu that to achieve the levels of funding needed for a sustainable pension solution will require reciprocal productivity measures.
But Siptu has written to the DAA to tell it that it believes the pension negotiations in their current form have reached an impasse.
"The SIPTU DAA Section committee ... are of the unanimous view that the current negotiation process is exhausted in that further direct engagement or the assistance of the Labour Relations Commission will not be able to progress the parties in any meaningful way," said a letter to the DAA seen by the Irish Independent.
