"The alternative is to stop improving and to instead do what the rest of the industry, including the UAW, has always done. But being industry average would make our safety 32% worse. We care too much about our team to go backwards."
I would also point out that the UAW has been on a bit of a anti-Tesla public relations blitz lately, which is something that creates public pressure on Tesla, but doesn't seems like it would affect the workers at all. If the conditions in the factory are really that sub-standard the workers themselves would know, they wouldn't need newspapers to tell them that.
