WestJet flight attendants begin a strike after negotiations between the union and the airline fail to reach an agreement. Both sides hold talks through the weekend, but the discussions do not produce significant progress on the central issue of compensation, according to reporting. The strike comes after a period in which the parties continued bargaining despite the lack of movement on pay-related terms. The union and WestJet do not indicate a settlement before the work stoppage, and the breakdown in talks is presented as the trigger for the strike. While the companies continue negotiations and related preparations may be underway, the immediate outcome is a labor disruption tied to the inability to agree on compensation. The reports characterize the negotiations as extensive, including continued discussions into the weekend, yet emphasize that the key sticking point remains unresolved, leading to the decision to strike.
