...sooner or later. Let's face it, Tesla is doing much better than you might think, given the short amount of time they've been in existence. They're very high profile, and Musk has a lot of money. That alone is enough to attract the inevitable parasites.
As to the claims that this worker is a UAW shill, he may be, or he may not. UAW certainly is not going to own it, nor will he, if this is true. He could simply be a disgruntled worker upset over X condition, and failing to make headway with local management, he is proceeding along his legally available options (rather than doing the easier thing and voting with his feet). HOWEVER, that's giving him and the UAW both a great deal of benefit of the doubt. It is entirely within the scope of union practises to use shills and other underhanded dealings (political donations, anyone?) to get what their leadership wants. It is completely plausible that he is, in fact, on the UAW's payroll. This has been the case longer than most of you posters have been alive.
Unions may have had their time and place once, but it sure as hell has passed them by. Nowadays, they exist to enrich their leadership, and keep their mediocre to piss-poor members employed, at the expense and on the backs of their members who actually give a shit about their job and perform well. Been there, done that, got the t-shirt and thanks to crooked leadership raiding the pension fund for personal gain, that's all I'll get for time served.
It'll be interesting to see how this plays out, anyway. Popcorn anyone?
