G.M. Sues Fiat Chrysler, Accusing It of Manipulating Union Talks

General Motors on Wednesday said it had filed a lawsuit accusing its rival Fiat Chrysler of trying to hurt it by manipulating contract negotiations with the autoworkers union.

Three former Fiat Chrysler officials have previously pleaded guilty to a range of charges related to their use of money that had been set aside for a training center that company ran along with the United Auto Workers union. Several U.A.W. officials have also pleaded guilty to various charges.

“The lawsuit exposes a multiyear pattern of wrongdoing by former F.C.A. executives revealed through the continuing criminal investigation by the U.S.,” G.M. said in a statement.

This is a developing story and will be updated.
