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 a Saturday announcement by Canadian Jobs Minister Patty Hajdu.

The union representing 10,000 Air Canada flight attendants said it will challenge an order to return to work and remain on strike.

Air Canada aims to resume flights after the CIRB, under Canada's Jobs Minister Patty Hajdu's directive, ended a strike affecting over 700 flights. The board ordered the airline and its flight attendants back to work by 2 p.
