While neither side is talking much publicly, it does appear that negotiations are still underway. In a very brief statement, the automaker simply says: "FCA US confirms that it has received strike notification from the UAW. The Company continues to work with the UAW in a constructive manner to reach a new agreement." The UAW seems equally receptive, and it says in a post on Facebook: "Negotiations with FCA continue. Your bargaining team is hard at work and we will continue to post updates when there is more to report."
If a strike happens, it could put a serious financial burden on FCA US. Economist Sean McAlinden from the Center for Automotive Research estimates the cost at as much as $40 million per week, according to Reuters. The union hasn't clarified at this time whether all of its workers with the automaker would stop working or if the picket lines would only be at specific plants.
The first tentative agreement posted to UAW members working with FCA US utterly failed in voting. Raises and a healthcare co-op would have been among the new benefits. However, the employees were upset that the proposed deal retained a two-tier wage structure, and they also didn't like the lack of details about rumors of major production changes.
