You don't have the right to what radio stations I listen to in my car, do you?
You don't have the right to tell me I can't have a box cutter in my car, do you?
What about a screw driver..and a tire iron? You gonna tell me I can't have those in my car too?
I have the right to "tell" you anything I want, you have the right to ignor me, and I have the right to fire you. In fact, most employees are "employees at will" which means they can quit for any reason at any time and I can fire them for any reason at any time or for no reason at all, provided the reason has nothing to do with their race, ethnicity, gender, age, or disability. Other than that, I can fire you because I don't like the color of your car, the shape of your tire iron, or your taste in music or talk radio. I can fire you because you drive a GM instead of a Ford or wear Levi's instead of Wranglers. Crap, I can fire you because you refuse to carry or possess a firearm.
