PARIS (Reuters) - Air France KLM shares slumped on Monday after the airline's biggest pilots union said over the weekend that there were risks of further strikes if pay talks with management did not resume.
Air France KLM shares were down 5.8 percent in early trading, the worst performers on Paris' SBF-120 equity index. The stock has fallen by around 40 percent so far in 2018.
"It's the risk of further strikes that's knocking down the shares," said Ion-Marc Valahu, a fund manager at Clairinvest in Geneva, who added he had steered clear of holding Air France KLM shares.
On Sunday, Philippe Evain, head of the powerful French SNPL pilots' union, threatened in an interview with Le Parisien newspaper 15 more days of strikes if the new Air France KLM chief executive did not restart talks over pay conditions.
KLM on Monday said its talks with Dutch pilots union VNV over better working conditions are in "a difficult phase".
Dutch pilots would consider going on strike if KLM fails to come up with better offers before Friday, Dutch newspaper De Telegraaf said, citing a letter from the union to its members.
Air France-KLM has been hunting for a new boss since the abrupt departure of CEO Jean-Marc Janaillac in May after staff rejected a pay offer aimed at ending the strikes which have so far cost the company 335 million euros (£298.67 million).
The French state is the biggest shareholder in Air France-KLM with a stake of about 14 percent. Delta Airlines and China Eastern Airlines each hold 8.8 percent.
A senior French pilot on Air France KLM's board of directors also said this weekend that the next CEO must not be beholden to external interests, as he criticized the possible choice of Air Canada's chief operating officer as preferred candidate.
