On Friday, the Air Line Pilots Association (ALPA) filed a complaint with the Canadian labor board against the airline WestJet for ignoring their duty to consult the union before hiring their new low-cost carrier, Swoop. WestJet has been expanding their international service and launching the low-cost carrier Swoop as a completely separate carrier. The key issue the APLA is pushing is that they believe Swoop pilots should be compensated the same as WestJet pilots.
