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.

The federal government is intervening to resolve a labour dispute with Air Canada and the union representing flight attendants.

The airline, Canada’s largest and the country’s flag carrier, estimates that with its roughly 700 daily flights suspended, some 130,000 customers will be impacted each day the walkout continues.
