Shares in Air France fell 14% in early Monday trading, after its chief executive said he would resign.
Air France-KLM shares suffered their biggest one-day fall in a decade, after the shock resignation of its chief executive over a pay dispute with staff.
In addition, the French government rejected the idea of a bailout for the airline.
Shares in the carrier fell as much as 14% on Monday, recovering to 10% by the end of the day.
French Transport Minister Elisabeth Borne said: “I’m worried about the future of Air France”. The carrier “is less competitive than its partner KLM and other European airlines.”
A wave of strikes at Air France has so far cost the company €300 million with no signs of ending.
Air France staff are demanding a 6% pay rise.
Management had offered workers a salary increase of 2% in 2018 and a further 5% over the following three years, which the unions rejected.
