UAW president Shawn Fain: "I truly find it pathetic when I hear Trump—a scab—talk about how he's going to bring back the auto industry and bring it back fast. When he was president, he didn't do a damn thing to help the auto industry. Plants were closing and left this country, and he did nothing to help it.”
Since they said “union” I assumed they meant the IBEW and decided to simplify it since I’m on mobile and just doing those links alone was a lot of work lol but this is fair to point out, though I’ll also point out that most of these unions shared a similar sentiment. You can see a lot of their statements on this with some quick searches. IAM and SMART are easy examples.
