Air Canada flight attendants are defying a government back-to-work order, continuing their strike and causing widespread disruption. The airline has suspended its plans to restart operations as hundreds of flights have been canceled, impacting thousands of passengers. The Canadian government has intervened, ordering the flight attendants back to work and seeking arbitration to resolve the labor dispute. Travelers are facing significant travel chaos due to the grounding of many flights, with the situation intensifying as the union remains firm in its strike action.
