so when your boss asks you to sign a non-disclosure, it's unconstitutional? clearly your freedom of speech is being violated
The US Constitution is an old piece of paper in a glass case. Nice tourist attraction, but of little relevance to the actual exercise of juridical power under the empire. (Thanks SKCOTUS!)
But yeah, non disclosure contracts certainly do constrain a person's freedom of speech. Some people think it's a-okay to stifle speech provided it's done in the name of private capital (as opposed to public authority). Whereas other people think that's not so okay. Value judgement etc.
