You seem so sure of your conclusions without any evidence (if you do have evidence then please provide it). I firmly believe in workers rights. I also firmly believe in evidence. California has some of the most employee friendly employment laws in the US. Germany some of the most in the EU. As long as these employees have reasonable severance and Tesla followed the law I don't see much room to complain. If however they were treated badly or illegally then I'm reasonably certain that a lawyer will help them on a contingency basis.
