Unions and management at jet engine overhaul firm Lufthansa Technik Airmotive have written to the Labour Relations Commission seeking assistance in negotiations on the threatened closure of the company with the loss of over 400 jobs. 

Sources said that at a meeting this morning, union representatives were told that a final decision on the fate of the plant will be taken at a board meeting of the parent company in Germany on 20 December.

Last month, management announced that the plant based in Rathcoole, Co Dublin, was to close by the end of February.

It then entered a 30-day consultation period - but union sources said that the negotiations had failed to yield a result satisfactory to unions - particularly in relation to redundancy terms. 

In a statement, Lufthansa Technik Airmotive Ireland confirmed that talks between trade union and employee representatives with management as part of a process to consider closing the company, which began on 18 November, are to be continued at the Labour Relations Commission. 

It said both sides had requested that the LRC agree a date for a hearing at the earliest opportunity.

The three trade unions involved are the TEEU, SIPTU and Unite.
