Fiat Chrysler CEO Sergio Marchionne, speaking today at the ceremonial opening of labor negotiations with the UAW, said pay increases for workers should come in the form of profit-sharing and other flexible compensation to avoid locking in higher costs during an industry downturn. Marchionne also stressed that he contemplated no reduction in the company's blue-collar workforce in the event FCA merges with another automaker to help reduce redundant product development costs.
