Air Canada says the Canada Industrial Relations Board has declared the strike by the company’s 10,000 flight attendants illegal and has ordered the union’s leadership to direct its members to return to work.

In the directive issued Monday, CIRB vice-chairperson Jennifer Webster ordered the union and its officers to end the “unlawful strike.”
