When/as more and more employees are paid to / held to a standard that keeps them a paycheck or two from insolvency, these mandated non-disclosure/-disparagement/-right-to-sue agreement, in return for severance pay/benefits, have taken on increasing pressure and importance. People in "the tech world" may not experience nor realize the immediate existential threat many people live under, with a job loss. These become another way in which "corporate America" is essentially stifling free speech and individuals' rights. Corporations lobbied heavily to be able to spend unlimited amounts in political campaigns. But, they won't let their workers say a word -- not even about their own direct life experiences.
