Dave Sauber, a former Shell Oil executive, has been named vice president of human resources and labor relations for Marathon Petroleum Corp.

The announcement adds an experienced union negotiator to Marathon’s workforce. Sauber, who earned a master’s degree in labor and industrial relations from Michigan State University, negotiated with the United Steelworkers International Union in 2009 and 2012 during his 27 years with Shell.

“It is a pleasure to welcome Dave to Marathon Petroleum's executive team," Gary Heminger, Marathon’s chairman, president and CEO, said. "His extensive human resources experience in our industry adds tremendous depth to our human resources organization as we execute our succession plans for the corporation's continued long-term success."

Marathon operates seven refineries that produce 1.8 million barrels per day. It also operates the Speedway chain of gas stations and convenience stores in nearly two dozen states.
