Employees at the Wal-Mart outlet in Saint-Hyacinthe, Que., the first store to successfully sign a collective agreement and stay open in Canada, have filed a request to decertify the union. UFCW Local 501 is “suspicious” of the 147 (out of 205) signatures collected on the decertification petition. Gregor Murray, a professor of industrial relations at the Université de Montreal, called it “a predictable event in the ongoing saga. Murray sees three plausible scenarios for why 70% of the unionized employees want out of the union. One, their contract, imposed by an arbitrator, is weak and favorable to Walmart. Two, they may be simply “disappointed” with their union and three, Walmart may have screened new hires for union sympathies.
