The work stoppages hit the Varel and Nordenham facilities in northern Germany, coming on the same day as industrial action at a plant in the southern city of Augsburg belonging to the parent company EADS. Airbus sought a court injunction against the strikes in Varel and Nordenham.
The company aims to group the three sites with some 6,000 staff at the end of the year in the new EADS unit Premium Aerotec. The works council has called the terms of the deal for employees "unacceptable". The company has asked staff to contribute to savings of €30 million ($38 million) in its operations, amounting to some €5,000 per worker.
Labour representatives say they should not bear the brunt of the restructuring programme, particularly without any guarantees from the company on jobs at the plants. The supervisory board of Airbus Germany plans to ink an agreement on the spinoff at a meeting Monday, works council officials said.
An Airbus spokesman declined to confirm the deadline but expressed confidence "that we will be able to reach a deal with the works council soon". With the creation of the new subsidiary, Airbus plans to create the world's biggest supplier for aeronautic structural components.
Airbus had originally intended under its vast Power 8 restructuring plan introduced last year to sell the three plants. But talks with the German company MT Aerospace failed earlier this year, as did attempts in France to sell the Saint Nazaire Ville and Meaulte factories. Plans for the new EADS unit Aerolia to assume the management of the two sites has also met with resistance from staff there.
The group has been hit by management instability, operational difficulties, and the strong euro, which makes its planes more expensive on international markets.
