230 Aer Lingus cabin crew who rejected a €97m cost reduction programme will only receive the legal minimum redundancy payment when they lose their jobs in a month's time.
All cabin crew will be made redundant after a 30-day consultation period.
Most of them will be offered immediate re-employment, but on lower pay and conditions.
Redundant cabin crew will get two weeks' pay per year of service, compared with six weeks in total for 440 staff accepting voluntary redundancy among pilots, administration, ground staff and craft workers.
Yesterday, the airline announced that it would have to secure cost savings through compulsory redundancies rather than by the voluntary deal that the cabin crew turned down by a margin of two to one.
It also said that it would not do any 'sweetheart' deal for the cabin crew, which was the only one of five groups to reject the restructuring agreement.
It is understood that the airline intends to make all senior cabin crew members, known as cabin managers, compulsorily redundant in an attempt to 'de-layer' the cabin crew organisation system.
The IMPACT trade union has said that the compulsory redundancy programme announced by Aer Lingus is 'brutal, targeted and unfair'.
The union is requesting that the Labour Relations Commission reconvene in order to 'find a mutual solution'.
In a statement this afternoon, the union says that despite assurances by the CEO of the airline Christoph Mueller, the measures 'look very much like a form of retribution against cabin crew for voting against the proposals'.
IMPACT says that it believes that the measures, if fully implemented, 'will damage the long term sustainability of the airline'.
Aer Lingus has said that it has no mandate from the board to enter further negotiations with cabin crew.
A spokesperson for Aer Lingus said that after four months in the Labour Relations Commission, there was nothing left to negotiate.
If I was crew I would be lobbying my reps incessantly for a negotiated settlement. Even if they are apparently temporarily indisposed.
Surely if these reps are suspended, or stuck downroute, they have MORE, not LESS time to attend union business; as they are claiming.
