The union for 10,000 striking Air Canada flight attendants said Monday they won’t return to work even though the strike, now in its third day, has been declared illegal.

The presidents of two major Quebec unions fear workers in the province could soon face the same treatment as striking Air Canada flight attendants under a provincial law passed in May.

"Major disappointment," said Zakaluzny, co-director of the ensemble. "We had put in the preparation work, people had taken … a week of holidays and all of a sudden they're going nowhere fast."
