Fianna Fáil has said the Transport Minister Leo Varadkar needs to intervene and prevent a strike from taking place at the national airline.
Yesterday, staff at Aer Lingus and the Dublin Airport Authority voted in favour of strike action over reduced pension entitlements.
The unions involved said they are willing to engage in negotiations with management and therefore they don't think the travelling public will be affected for the time being.
But Fianna Fáil's Transport Spokesperson, Timmy Dooley, has said Mr Varadkar needs to step in and ensure there is a swift resolution to this dispute.
