The president of the United Autoworkers union is brash, threatening, loud and direct. Shawn Fain is trying to bargain a new contract for his members. But six weeks into what he calls a "stand up" strike, taking down plants without notice, there's no deal yet. Is he overplaying his hand, digging in for the best new contract after GM, Ford and Stellantis have raised their offers, or is Fain just vain, staying in it to stay in the public eye?
