Mr. Wagoner began running the North American division in April 2005, saying: "Given the challenges we face in North America, it makes sense for me to assume control ... and shorten the lines of communication and decision-making." Mr. Wagoner succeeded Gary Cowger in that capacity last year and allowed Mr. Cowger to focus on global manufacturing and labor.
Contentious labor talks
Mr. Clark, 51, joined GM's Pontiac arm in 1973 and held several engineering and manufacturing assignments. He had been president of GM's Asia Pacific since 2004 and has held top jobs in GM de Mexico. In 2001, he was named VP labor relations in Detroit and served as chief negotiator with the United Auto Workers union during 2003 contract talks. GM is expected to face contentious labor talks next year. Mr. Wagoner announced last November a vehicle capacity reduction plan to cease operations at nine assembly, stamping and powertrain plants. GM had inked a historic agreement with the UAW a month before to trim its health-care costs.
Mark LaNeve, VP-vehicle sales, service and marketing in North America, who had reported directly to Mr. Wagoner, will report to Mr. Clark beginning July 1, a spokesman said.
