UPDATE: Unifor Ratifies GM Labor Pact by 86% Margin

Today Canadian auto workers ratified a new four-year labor contract at General Motors Co.’s CAMI assembly plant and are returning to work at 7 p.m.

The Unifor labor union says the deal was accepted by 86% of the hourly workers who voted, thereby ending a strike that began on Sept. 17.

The pact does not include a guarantee sought by Unifor to name CAMI as GM’s lead factory for the popular Chevrolet Equinox crossover vehicle. The designation would have made the factory first to add Equinox workers and the last to lay them off. Nor did GM commit to add future products or jobs at the Ingersoll, Ont., facility.

But the union said it did gain contract language that would force GM to pay an additional $100 million if the company eventually decides to close the facility. The agreement also gives workers a 4% wage hike, a C$6,000 ($4,800) bonus and C$8,000 ($6,400) in additional lump-sum payments over the four-year term of the agreement.

The deal leaves CAMI’s long-term future as doubtful as ever. In April GM added Equinox production at two plants in Mexico. The carmaker also cut the hourly workforce at CAMI by 600 people when it relocated output of the GMC Terrain, a variant of the Equinox, from Canada to Mexico.
