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.

To complete the safe wind-down of our complex operations, we began a phased reduction of most of our flight schedule,” Air Canada said.

A walkout by flight attendants ended after about 12 hours with the imposition of binding arbitration. But getting travel back to normal will take days.
