Aer Lingus and DAA members of SIPTU to strike on Monday

Aer Lingus staff belonging to the SIPTU union are to go on strike next Monday over planned changes to their pension scheme.

Members who work at Dublin Airport Authority (DAA) are also taking part in the industrial action.

SIPTU said the decision had been reached following the failure of both companies to put forward any meaningful proposals to resolve the dispute.

Flights and services at Dublin, Shannon and Cork airports could be affected.

After a meeting on Wednesday morning, the industrial action committees of Aer Lingus and the DAA said that there was "anger and dismay" among members over the threats, legal and otherwise, that they claimed had been made by the employers over recent days.

SIPTU sector organiser, Dermot O'Loughlin, said: "Industrial action will proceed on Monday as expected proposals from Aer Lingus and the DAA that could have helped resolve this dispute have not materialised.

"Both companies have, for many years, paid significantly low contributions into the pension fund. Now they have abandoned their responsibilities to thousands of our members by refusing to put the required extra monies into the scheme.

"SIPTU remains committed to any meaningful process that can bring about a fair and reasonable outcome for our members."

The union said a further meeting of its industrial action committees will take place on Thursday morning.
