Siptu agreed this morning to stay in the process established by the National Implementation Body (NIB) to find ways of achieving the €20 million savings being sought by Aer Lingus.
The company has sought the savings under a controversial plan that almost led to industrial action several weeks ago.
Last month, the implementation body said that negotiations on change and talks in relation to Shannon airport had resulted in Aer Lingus and Siptu identifying savings of some €10 million.

Today, Aer Lingus branch organiser Teresa Brannick, said: "Shop stewards considered the proposals made by the NIB on December 21st and are happy it is achieving our objective of identifying alternative savings to the proposed cuts in pay being sought by the company."
"We are committed to the process, which has already identified some €10 million in savings in the areas where Siptu has members."
In a statement, Aer Lingus said it noted the outcome of the SIPTU Shop Stewards meeting today and welcomed "their leadership in this important process."
"The company is fully committed to continuing to engage positively with the Union to bring this process to a close in line with the deadlines recommended by the NIB.
Aer Lingus' controversial plan to make a Eur20m saving led to industrial action.
"Aer Lingus is now calling on the other unions in the airline to engage in a similarly positive manner so that the targeted staff cost efficiencies and productivity gains may be realised for the benefit of all stakeholders."
Separate to the NIB process, Siptu has referred the pay freeze imposed unilaterally by the company on employees on October 1st, 2007, to the Labour Relations Commission and the Labour Court. The union says the pay freeze is "a clear breach" of the national agreement Towards 2016.
An early hearing of the case is expected. This does not interfere with the NIB process.
