Gephardt has also served as a lobbyist for Boeing. He is a labor consultant for Spirit Aerosystems and sits on its board of directors. In these roles, Gephardt has presided over an aggressive anti-union campaign that has bewildered many of his traditional political allies. In July 2011, Spirit Aerosystems walked out of negotiations with the union that represents its engineering, technical and professional workforce. The union subsequently voted down the company's last contract offer, with 96.5% voting no. The company did not change its contract offer significantly after this rejection and relations with its workforce have been contentious ever since. With negotiations at a standstill, production schedules for 2011 and 2012 were threatened.
