Air Canada flight attendants to defy back-to-work order and remain on strike

Union to challenge order issued less than 12 hours after start of action that has left more than 100,000 travellers stranded

Air Canada's flight attendants plan to remain on strike, their union has said, defying government efforts to force them back to work and into binding arbitration over a dispute that has left more than 100,000 travellers stranded around the world during the peak summer travel season.

About 10,000 flight attendants who work for Canada's largest airline walked out on the job early on Saturday amid a bitter dispute over what the union has described as poverty wages" and unpaid labour.
