Canadian auto workers

GM Canada

More than 2,700 union workers at GM's CAMI Assembly Plant in Ingersoll, Ontario walked off the job early Monday morning.

The plant builds GM's best-selling crossover, the Chevy Equinox.  GM also builds the Equinox in Mexico. 

Unifor members at a rally in Canada

Unifor will sit down at the bargaining table with General Motors first in its upcoming contract talks with Detroit-based car companies.

The talks could be even more tense than usual. 

That's because union leaders suspect GM may have long-term plans to pull more jobs out of Canada. 

Unifor wants GM to promise new models for its Oshawa plant, but GM is balking. 

Harley Shaiken is a labor expert at the University of California-Berkley. He says it makes sense the union is worried about losing more jobs.
