OTTAWA — Air Canada flight attendants remain on strike despite back-to-work orders by the Canada Industrial Relations Board.
Over the weekend, the federal government asked the board to send the two sides to binding arbitration and order an end to the job action. But the union is challenging the order in Federal Court, and the 10,000 workers have stayed on strike.
This morning the labour board declared the strike unlawful and ordered the union's leadership to tell the flight attendants to go back to work.
