Wearing a UAW hat and a sweatshirt with the presidential seal, Biden triggered broad applause when he told the crowd of about 200 people that they “deserve a significant raise.”

“Let’s keep going,” he said later, before walking among the picketers to give out fist bumps and pose for selfies. “You deserve what you’ve earned. And you deserve a whole hell of a lot more than you’re getting paid now.”
