Got accepted to Nexon focus group 2/21 <-- Note This Is In The Past

I was merely basing it off the fact that you can't enforce a contract that would break a law, for instance I could never enforce a contract that made someone my slave regardless of whether or not they signed it. I would think that signing an NDA would go against our first amendment right to free speech I am however, as I said earlier not a lawyer though I would love to hear from someone more knowledgeable on the subject.

NDA agreements are perfectly legal in the United States, given that they do not enforce "illegal penalties" for divulging information (ex. Nexon can't kill you, but they can fine you, etc.)

Moreover, they are common practice for many employers, especially in the high-tech sector. It's often used to avoid trade secrets from being leaked out by employees who are laid off / fired.
