More than 600 auto workers protested the outsourcing of their jobs to Mexico outside of Ford Motor Company's corporate headquarters on Friday. United Auto Workers local 36 organized the protest in part because the company is increasing the new car lines being built in Mexico. The union also believes the company may be planning to shut down it's assembly plant in Wixom, Michigan. Since 2002 the plant has lost 55 percent of it's hourly workforce and production of the Thunderbird will be phased out next year.
