Silicon Valley has long been the center of the universe for technology workers. If you want to play on the big stage for software engineers, the storied northern California tech hotbed, first named publicly in the early '70s, remains the place to be. But what if you found out that all of the major tech companies there were in cahoots to suppress your salary? What if you had proof that the heads of companies like Apple and Google were slinging emails around, asking each other to not hire you? You'd probably do what those very companies seem to love to do: you'd sue.
