More than 10,000 Air Canada flight attendants who went on strike early Saturday will be ordered to return to work by the Canada Industrial Relations Board (CIRB), according to an announcement Saturday by Canadian Jobs Minister Patty Hajdu.

Air Canada is facing a crisis after its flight attendants walked off the job over the weekend and rejected a government order to return to work.The union representing 10,000 flight attendants at Canada’s biggest airline said it would request that a judge block a government order Saturday that imposed binding arbitration to resolve a labor dispute between the union and carrier.
