WestJet workers at airports in Calgary and Vancouver have voted in support of a strike if they cannot reach a deal with the airline.
Unifor says the local representing more than 700 baggage and customer service agents, among other employees, have voted 98 per cent in favour of a strike.
They could walk off the job as early as July 27th.
Unifor spokesman Scott Doherty says wages are the key issue in talks over the group's first collective agreement with the carrier.
The strike vote comes as airlines and airports have struggled this summer with the resurgence in travel following the lifting of COVID-19 restrictions.
