Unions representing Luxair's staff are calling for government mediation after the 18 April collapse of negotiations on renewal of collective labour agreements.
They say the Luxembourg flag carrier refuses to begin discussions until certain "draconian" concessions are made by the unions on behalf of their members.
As a result the unions sent a letter today to the National Conciliation Office, a government body attached to Luxembourg's ministry of employment requesting that it acts as an intermediary in order to reach a compromise with the airline.
Under Luxembourg law, the unions cannot call a strike without the Office's permission, but they say that should this be given, the strike would likely occur during the peak summer schedule.
In March, Luxair warned that its survival depends on cutting its cost base in order to generate an additional €25 million ($33 million) annually from 2015 and as a result would apply cost-cutting measures during the renewal negotiations.
