SIPTU shop stewards will meet tomorrow to discuss how to go forward after members rejected Aer Lingus' cost-cutting plans by three to one.
The union will also continue to be in contact with Aer Lingus management.
Aer Lingus management met with staff members today to discuss the proposed cost-cutting measures.
In a statement, Aer Lingus said that it was aware some issues had been raised about 'the shape of new work rosters'. It said it was addressing these concerns directly with staff in a series of meetings that began this morning.
Last night the 1,800 workers employed in Aer Lingus's ground operations - including check-in, loading and catering - voted by a margin of three to one against the new work practices, which were intended to save the airline up to €20m a year.
Early last year Aer Lingus chief executive Dermot Mannion promised shareholders that he would implement the staff cost savings from the beginning of 2008.
But, so far, none of the promised savings have materialised. This is because management and unions have been bogged down in negotiations about new work practices, rosters and other staffing arrangements.
SIPTU's 1,800 ground staff members had already voted to take industrial action if changes in working arrangements were introduced without agreement.
After marathon negotiations five weeks ago, a strike was averted when SIPTU officials and management reached agreement on a package of cost-cutting proposals which were to be put to a ballot of members.
