Irish flag-carrier Aer Lingus is to resorting to arbitration to reach a cost-saving agreement with its pilots.
The airline has accepted an invitation to the process from the Irish Congress of Trade Unions and the Irish Business and Employers Confederation.
Aer Lingus claims pilots' demands are obstructing its bid to restructure the airline's cost base.
"The objective of this [arbitration] process will be to work to finalise agreement with [the Irish Airline Pilots' Association]," it states.
"Aer Lingus looks forward to a vigorous and productive engagement, and for its part will make its best endeavors to reach an early agreement."
IALPA has rejected the airline's accusations, claiming that it has offered a package of measures comprising salary cuts, voluntary redundancies and a productivity increase.
