Contract talks between Fiat Chrysler and the United Auto Workers union are continuing after both sides extended their current contract on an hour-by-hour basis.
The contract officially expired at midnight Monday. Shortly after that, FCA and the UAW said they would extend it while they continue negotiating a new four-year agreement.
Ford and General Motors have extended their contracts with the UAW indefinitely.
The UAW picked Fiat Chrysler as its target company in the contract talks. That means a deal with FCA could set a general pattern for contracts at General Motors and Ford. FCA could also be hit with a strike if negotiations stall.
All three companies officially kicked off bargaining for new four-year contracts in July. The contracts cover around 140,000 U.S. factory workers.
