Air Canada flight attendants defied a back-to-work order, continuing their first strike in 40 years. The Canadian Union of Public Employees (CUPE) rejected the government-mandated arbitration, claiming it was unconstitutional. The strike, impacting 130,000 daily travellers, centers on compensation for ground time and wages. Air Canada plans to resume flights Monday evening. The union cites insufficient wage increases to match inflation and the federal minimum wage as key issues. The government's next steps remain unclear.
