Air Canada Chief Executive Mike Rousseau said on Monday that the airline was "amazed" by the decision of its flight attendants' union to defy the Canada Industrial Relations Board, which has declared the union's strike unlawful.

The dispute exposes several fault lines in Canada around work, how we value it and how the law impacts workers.

Over 100,000 passengers have been stranded due to Air Canada flight attendants participating in a major strike against the airline.

Lawyer Sundeep Gokhale says there is a ‘high possibility’ that the Canada Industrial Relations Board will get involved if Air Canada flight attendants strike.
