Talks will take place today between union representatives and management at Aer Lingus aimed at resolving the row over cabin crew rosters.
IMPACT members staged a one-day strike last Friday, causing more than 200 flights to be cancelled, disrupting the travel plans of up to 40,000 people.
The trade union called the strike because cabin crew say they are frustrated and exhausted from working erratic rosters.
They want a rostering arrangement of five days on and three days off - similar to the work pattern of Aer Lingus pilots.
The pilots union IALPA has come out in support of the their Impact colleagues.
Last week Aer Lingus invited IMPCT to talks - the union accepted, but it was not enough for them to call off Friday's strike.
Aer Lingus retaliated for the work stoppage by stripping cabin crew of the heavy discounts they get on unfilled seats.
The union did not respond to the latest move by the airline. IMPACT said it will not comment until after today's talks.
The meeting between the union and Aer Lingus begins at 1.30pm this afternoon.
