On 17 January 1957, the Porsche automobile company employed Peiper in Stuttgart. In the course of his employment, Italian trade union workers formally complained that Peiper was unacceptable as a co-worker because he remained a Nazi and because of the wartime Boves massacre committed by his command, the Kampfgruppe Peiper, in Italy. An owner of the car company, Ferry Porsche, personally intervened to promote Peiper into a management job, but the trade unions legally refused to work with Peiper; despite the friendship with Porsche, and because of lost sales of cars in the U.S. — for employing a Nazi war criminal — the Porsche automobile company dismissed Peiper from his employment.
