With a threatened strike hanging over them, negotiators from Fiat Chrysler Automobiles NV and the United Auto Workers union continued to meet on Wednesday afternoon, a Fiat Chrysler spokeswoman said. The U.S. union on Tuesday called for a strike against Fiat Chrysler’s U.S. operations at 11:59 p.m. EDT on Wednesday (0359 GMT Thursday) unless a new agreement on a four-year contract is reached or there is movement toward one. A union spokesman gave no details of the talks including whether the company was willing to sweeten the deal it offered the UAW that was approved Sept.
