SIPTU has said that there will be no industrial disruption to Aer Lingus flights or Dublin, Cork and Shannon Airports before Christmas.
The statement comes despite the fact that SIPTU members in the airline and the Dublin Airport Authority have decided to ballot for industrial action in a row over pensions.
SIPTU official Dermot O'Loughlin said despite being convinced of the justice of their cause in pursuing their pension entitlements, staff at Aer Lingus and the airports had no wish to inconvenience the hard-pressed public at the busiest time of the year.
It is understood that SIPTU President Jack O'Connor has authorised the holding of the ballots in the DAA, Shannon Airport and Aer Lingus.
The DAA ballot will commence on Saturday, with the Aer Lingus ballot starting shortly afterwards.
However, regardless of the outcome of the ballots, no industrial action will commence until after the peak Christmas/New Year period.
