I'm having a difficult time finding the numbers of unionized and non-unionized auto workers in the US. Lots of propaganda both for and against unionized autoworkers but little useful information. More and more that seems to be the state of the internet; lots of articles and information but little that is useful and what is useful is difficult to find. Overall it looks like 2/3 of auto workers are unionized? And the split is the Big 3 versus everyone else. And it looks like the big difference is pensions. And the fact the the Big 3 make shitty cars and ginormous trucks that make little sense to me. An interesting article about the BMW plant in Spartanburg SC finds fault with both UAW and BMW. That's the plant where I heard rumors that the German BMW workers threatened to strike on behalf of the South Carolina workers, partially to also protect their own situation though. https://www.wsws.org/en/articles/2018/09/06/spar-s06.html https://www.wsws.org/en/articles/2018/09/06/spar-s06.html I would also love to learn more about unions and workers' councils in Germany, as they sound less antagonistic with management while still managing to look out for workers. I wonder if something like that could work in the US. Either way, investigating either of these topics would be a major undertaking. UAW benefits sound great but I sure would not be proud to work at Chrysler.
