Please do not confuse "right to work" which is a union issue, with "at will", they are different under the law.

Again wrong. The law protects the employee from prosecution for violating a law. It cannot protect an employee from company policies. And I know 30.06 only applies to "premises" (the legal definition). The parking lot law would protect you from being fired for that reason, but it doesn't matter.

Texas is an "at will" employment state. You can quit anytime you want, and you can be let go any time they want. No reasons have to be given. Example - layoffs.

Now, you have brought up discrimination issues. Yes, these are valid, and an employee can sue and try to prove this, and receive damages. But it doesn't change the basic "at will" situation.

Wrong. In Texas, you can be fired for any reason. In fact, you can be fired for no reason. You can also quit with no notice and no reason.

But you cannot be prosecuted. That's the difference.

You can be prosecuted if you violate a 30.06 sign.

Yes, they can do that. And they can fire you for violating company policy. In fact, they can fire you without any reason. And of course, you can quit for any reason. Texas "free will".

Can they call the cops and have you arrested? No. You would not be breaking the law, if you left your weapon in your car.
How would they know?

However, if they posted 30.06 on the buildings, or asked you to leave and you didn't, you would be guilty of trespassing.
