General Motors Co (GM) announced on Monday that its heads of human resources and communications are leaving the company "to pursue other interests."

John Quattrone, who joined GM in 1975, will succeed Melissa Howell as senior vice president, global human resources.

GM did not immediately name a replacement for Selim Bingol, senior vice president, global communications and public policy.

Quattrone's appointment as human resources chief is effective immediately, as are the departures of Howell and Bingol, GM said.
