Union workers at Ford Motor Co.'s Rouge complex in Dearborn will vote this week on whether to accept work rule changes that the automaker and UAW officials say are necessary to secure future work at the site and to protect jobs. The proposal is controversial because some workers resent Ford's asking for changes to work rules outside the normal contract bargaining cycle. "I can see why workers would be opposed to it," said professor James Martin of the School of Business Administration and identified as "a labor professor" in the story. "It's gotten to be very tough to be a worker in the auto industry when all they ask you to do is to take concessions." He also pointed out that when factories can't be competitive they stand to lose work to foreign countries or non-union companies.
