WestJet flight attendants have approved a strike mandate, authorizing a work stoppage if the parties do not reach a new collective agreement. The union representing the cabin crew tells members they can strike if contract negotiations fail, with the possibility of thousands of workers walking off their jobs in fewer than three weeks. The decision is communicated in an update to members and is reported in coverage based on information obtained from the Canadian Press. The agreement process involves negotiations over contract demands, but specific terms are not detailed in the reports provided. The mandate gives the union leverage to push for its proposals during the remaining bargaining period. If a new deal is reached, the strike would be avoided; if not, the authorization allows the union to proceed with job action subject to the applicable labour process and timing. The reports frame the vote as a step that raises the risk of disruption to WestJet operations and passengers if negotiations continue without agreement.
