The Financial Post reports in its Tuesday edition that a federal arbitrator has ruled that WestJet's unionized pilots will also fly its new ultradiscount carrier Swoop that is set to launch next week. A Canadian Press dispatch to the Post quotes Rob McFadyen, chairman of WestJet's Air Line Pilots Association, as saying the decision means the airline can no longer outsource Swoop flying. Swoop will recognize the union as the exclusive bargaining agent for all Swoop pilots, who will be on the airline's one seniority list and fly aircraft at Swoop terms and conditions. WestJet and the union will now make a joint application to the Canada Industrial Relations Board to amend the pilots association's bargaining certificate to include Swoop flying. The parties also agreed that WestJet and Swoop are common employers. The two sides scheduled mediation and arbitration dates over the summer to address all remaining issues. The threat of a strike by pilots was averted two weeks ago when the airline and union agreed to a settlement process and, if necessary, to use final and binding arbitration. WestJet said it recognizes and respects the interim order that WestJet pilots should be able to operate Swoop aircraft.
