The union representing approximately 4,400 WestJet flight attendants [1] has issued a 72-hour notice of intent to strike [2].

This labor dispute threatens to disrupt air travel across Canada, particularly at major hubs such as Toronto Pearson International Airport and Calgary [3]. A strike would likely result in widespread flight cancellations and delays for thousands of passengers.

The notice comes as contract negotiations between the union and WestJet have intensified [4]. While the union has set a deadline for a new agreement, the airline has responded by issuing a lockout notice [5].

If a deal is not reached, the earliest potential strike date could be as soon as Sunday [6]. The lockout notice from the airline allows WestJet to prevent employees from working if the labor dispute escalates further.

The conflict centers on ongoing disagreements over the terms of the flight attendants' contract. The union is seeking improved terms as part of the current negotiations [4].

Travelers are advised to monitor their flight statuses as the 72-hour window progresses. The potential for a walkout remains high unless both parties reach a compromise before the deadline expires [2].

The simultaneous issuance of strike and lockout notices indicates a critical breakdown in collective bargaining. Because WestJet operates as a primary carrier for both domestic and international travel in Canada, a work stoppage would create a significant logistical bottleneck at Pearson and Calgary airports, forcing passengers to seek alternative carriers during a high-traffic period.
