Aeroports de Montréal (ADM) warned passengers to check their flight status before heading to Montreal-Trudeau airport and to expect possible delays as unionized refuelling personnel launched a strike at 11 a.m. Tuesday. “Passengers at YUL Montréal-Trudeau International Airport find themselves, through no fault of their own, in the midst of a labour dispute between Swissport Fuelling and its employees responsible for refuelling aircrafts,” the agency said in a communiqué posted minutes after the walkout began. “Since the announcement of a strike, ADM has spared no effort to enable Swissport Fuelling to rapidly deploy its contingency plan, including providing managers with access to restricted zones so that they can ensure the continuation of aircraft refuelling activities at YUL.” Tuesday’s strike comes after the unionized personnel overwhelmingly rejected an offer from management made last week. Salaries and work-life balance are major issues in negotiations, which have been going on since the spring.
