I have worked in multiple wafer fabs in Arizona, there are plenty of workers but the way they do things is strictly through contractor companies where your not guaranteed a position within the actual company at all, your contract lasts for 6 months, or a year, and then hopefully when it's done the contractor you were working with has another gig for you at another Fab, or you just go with a different contractor for a different assignment. Wages are barely above minimum, there are no advancement opportunities, there's no raises, the shifts are 12 hours and most of the time the only thing that's available is overnight. The problem isn't that there aren't workers, the problem has never been that there aren't workers, the problem is that these jobs are unsustainable for workers to survive with current business practices, and rather than attempting to fix that their plan is to bring in an even more exploitable class of people.
