The National Implementation Body is to hold separate meetings with unions and management at Aer Lingus today to clarify the position of both sides in the dispute over proposed cost-cutting measures.
The State's industrial relations trouble-shooter is expected to issue recommendations aimed at resolving the dispute no later than next Monday.
A planned strike by staff at the airline was suspended earlier this month pending the outcome of a NIB review process to deal with the row over the €20 million cost-saving plan.
Under the NIB process, a mediator was appointed to conduct an analysis of the company's cost-cutting proposals and their implications for staff.
Unions insist that airline moves to withhold pay increases due under Toward 2016 until proposed cost-cutting measures are implemented are in breach of the agreement.
But the company says it is operating in a highly competitive market and its future depends on an ability to respond to the changing environment.
Its position, therefore, is that until cost-saving measures are implemented, a pay freeze will apply to all employees.
