WASHINGTON United Auto Workers President Shawn Fain will tell a Senate Committee on Tuesday the union plans to aggressively organize non-union U.S. auto plants after winning new contracts with the Detroit Three automakers.

"For decades, non-union auto companies have used fear, uncertainty, and division to break union drives in our industry," Fain will tell the Senate Health, Education, Labor and Pensions Committee, according to written testimony seen by Reuters. "I’m here to promise you that those days are over."

The UAW for decades has unsuccessfully sought to organize auto factories operated by foreign automakers.
