Aer Lingus plans to close its maintenance hangar at Shannon airport.
The Irish carrier is "at an advanced stage" in transferring the lease for the facility, which was approved by the executive board earlier this month, according to the Unite union.
While the move is "likely to be finalised in the coming weeks", the decision has not been communicated to staff, the union adds.
Some 70 employees are currently working at the hangar.
Local media have reported that Aer Lingus plans to keep a small line maintenance unit operating at the regional hub.
The hangar, which is owned by the outgoing airport operator, Dublin Airport Authority (DAA), is to be handed over to an unnamed third party.
The Irish government decided earlier this month to place Shannon airport under new operating company together with the Shannon Development agency. However, Cork airport will continue to be run by DAA.
Aer Lingus could not be immediately reached for comment.
