Aer Lingus management has revealed details of the rescue plan it hopes will save the national airline from bankruptcy.
2,026 full-time staff are to lose their jobs as part of the package.
470 of those are cabin crew, 150 are pilots and 550 are administration and clerical staff.
38% of the company’s management staff will also be laid off to keep the airline profitable following the aviation crisis exacerbated by last month’s attacks in the United States.
Aer Lingus chief executive Willie Walsh said the airline’s long-term future will be guaranteed if this plan is implemented in full by the end of the year.
He told workers the company's cash reserves would be exhausted by 2002 if the plan is not adopted.
Mr Walsh added that the plan would see Aer Lingus return to profitability by 2003.
Unions representing the laid-off staff have described the package as the starting point for negotiations over the level of redundancies.
