The board of Aer Lingus has approved a three-year business plan for the airline during a meeting in Dublin.
In a statement, the board said the plans outlined what is needed for the company to survive in a low fares environment.
The details of the plan are not expected to be made public until after a meeting with unions tomorrow.
IMPACT and SIPTU have already said that they would oppose any compulsory redundancies.
The two biggest unions reacted angrily to reports that Aer Lingus is to shed 1,300 jobs.
Mick Halpenny, the National Industrial Secretary of SIPTU, said no clear case for any redundancies had been made and warned that any attempt by the company to force change would be resisted.
Meanwhile, the Minister for Transport, Seamus Brennan, said if there were to be job cuts in Aer Lingus he did not see any reason why they should not be on a voluntary basis.
Speaking to RTÉ News, Mr Brennan said Aer Lingus had succeeded spectacularly over the last three years in getting agreement on staff reductions, and he would not like there to be any compulsory redundancies.
