Legal Question in Constitutional Law in Kansas

Your question is hard to answer because it contains so few details. But you're probably worrying for no good reason.

Even if the papers you signed waived some of your rights, that waiver was almost certainly limited to issues involving the organization you worked for. For example, you may have waived your right to a jury trial involving disputes with that organization, but you could not have waived your right to a jury trial overall. You also may have agreed not to reveal information about the business or express negative opinions about them, but that agreement would not have any other effect on your freedom of speech.

The organization should have this form in your personnel file. If you ask for a copy, they should give it to you -- or at least let you come in and look at it.

If you've asked and they didn't know what you were talking about, perhaps you're mistaken about what happened. Maybe the form wasn't related to your employer even though you were at work when you signed it.

In the future, review papers before you sign them. If you don't understand what they're for, ask. Make a copy if you can, and ask the other party to give you a copy if you can't make one yourself.
