UAW Calls Strike on One of GM’s Largest and Most-Profitable Factories

The United Auto Workers expanded its strike against Detroit’s automakers with a walkout at one of General Motors’ largest and most profitable factories, marking the second straight day of escalation by the union.

About 5,000 unionized workers walked out of GM’s Arlington, Texas, assembly plant Tuesday morning, the union said. The plant makes several large sport-utility vehicles, including the Chevrolet Suburban and Tahoe, GMC Yukon and Cadillac Escalade, which are GM’s highest-profit-margin vehicles globally.
