Approximately 4,400 WestJet flight attendants began a national strike on Sunday, causing the cancellation of regular flights across Canada [1].

The labor action disrupts one of Canada's largest airline networks and leaves thousands of passengers stranded during the peak summer travel season. The walkout follows a prolonged failure to reach a collective bargaining agreement between the employer and the crew.

The strike officially commenced at 00:02 Rocky Mountain Time on Aug. 2 [3]. The action was announced from Calgary, Alberta, where the airline is headquartered [2].

This escalation follows a decisive vote on July 15, when 99.4% of the flight attendants, represented by the SCFP 8125 union, voted in favor of a strike mandate [2, 6]. The union moved forward with the strike after negotiations for a new contract failed to produce an agreement [4, 6].

Flight disruptions began before the official strike date. On Saturday, the airline cancelled 81 flights [5]. Since the labor dispute intensified, WestJet has cancelled more than 300 flights in total [3].

While some reports indicate all regular flights are cancelled until further notice, other accounts specify the disruption as hundreds of flights [1, 3]. The airline has not provided a timeline for the restoration of full service as the 4,400 crew members remain off the job [1].

The overwhelming 99.4% strike mandate suggests deep-seated dissatisfaction among the crew, indicating that a quick resolution is unlikely without significant concessions from WestJet. Because the strike occurred during the high-demand August travel window, the airline faces not only immediate operational collapse but also potential long-term reputational damage and lost revenue from diverted passengers.
