During the 2011 round of negotiations, the employer changed some of the working conditions of CUPW urban unit members starting on May 30, 2011, until Bill C-6 came into effect on June 27, 2011. The Union filed National Grievance N00-10-00001 to challenge this decision. The bill provided for resuming postal service and extending the collective agreement as of February 1, 2011 until a new collective agreement came into effect.
Arbitrator André Bergeron rendered a final decision in the matter on October 30, 2014, in which he allowed the great majority of the Union’s claims. Following an extensive legal battle before Quebec tribunals, the parties finally reached a settlement on August 21, 2018.
