The European Court of Justice (the "ECJ") has ruled that, in certain circumstances, when a subsidiary company is wound up, its employees will transfer automatically to its holding company.

What happened?

Air Atlantic SA ("AIA") was a Portuguese company operating in the aviation sector. It had been providing charter (or non-schedule) flight services since 1985.

On 19 February 1993, AIA was wound up. During the winding-up, several of AIA's employees were dismissed as part of a collective redundancy.
