DETROIT (Great Lakes News) – More than 49,000 members of the United Auto Workers union are on the picket line after contract talks with General Motors broke down early Monday. Union members walked out of factories at 33 plants nationwide. Twenty-two parts warehouses are also standing in solidarity with their fellow workers. Union officials say the strike is a last resort after sticking points like health care and fair wages kept stalling talks. GM officials said the company offered the union higher wages and $7 billion worth of factory investments tied to hundreds of new jobs. Both sides will return to the bargaining table Monday at 10 a.m. to continue hammering out a deal for a four-year contract.
