Airbus is exploring restructuring plans involving the possibility of “deep” job cuts as it braces for a prolonged coronavirus crisis after furloughing thousands of workers, industry sources said, though no decision is imminent. Chief Executive Guillaume Faury is expected to update managers on Thursday after warning staff last month that the firm’s survival was at stake due to a slump in demand. Under French law, Toulouse-based Airbus cannot disclose restructuring plans internally before consulting trade unions through a formal exercise not expected before the end of May.
