Talks aimed at resolving the rosters row at Aer Lingus will resume this morning at the Labour Relations Commission.
The dispute is now entering its third week and has resulted in around 10% of Aer Lingus flights being cancelled, disrupting the travel plans of thousands of passengers.
Three hundred members of the cabin crew have been removed from the airline's payroll.
IMPACT spokesman Niall Shanahan said: "IMPACT remains focussed on finding a solution to the issues at the heart of this dispute."
