The National Post reports in its Saturday, Aug. 1, edition that WestJet is parking aircraft as its flight attendants face a possible strike by Sunday. The Post's Mason Kossack writes that WestJet said it has not reached an agreement with the union. Parking planes helps WestJet maintain operational control and reduces the risk of stranding guests and aircraft. Flight attendants, represented by CUPE Local 8125, served a 72-hour strike notice Thursday. WestJet issued a lockout notice of its own shortly after, which would let the airline shut the operation down rather than wait to be struck. Either notice can take effect at 12:01 a.m. MT Sunday. At issue is how flight attendants get paid. The union says the current pay structure leaves hours of work uncompensated and wants pay for all time worked, a campaign it calls Unpaid Work Won't Fly. "There's still time to avoid a strike," CUPE 8125 president Alia Hussain said Thursday. CUPE 8125 represents 4,400 Westjet flight attendants. Members voted 99.4 per cent in favour of a strike mandate on July 15, on a turnout of 97.3 per cent the union said was its highest ever. That vote gave the bargaining committee the power to call a strike. It was not a commitment to walk out.
