The federally appointed watchdog overseeing the United Auto Workers union found that its president, Shawn Fain, retaliated against a top officer and improperly used his authority, including in ways that would benefit his fiancée and her sister.

 

New York attorney Neil Barofsky, the monitor overseeing UAW activities, said in a report released on Thursday that Fain retaliated against a union official, Rich Boyer, after Boyer pushed back against some of Fain’s actions.
