For somebody whose avatar and posts intimates some knowledge of liberty and of the constitution, you say profoundly stupid things. The constitution was developed to protect people from the government. You are free to call your boss a flaming a-home, you will not be tried as a criminal. You will be fired, however and your first amendment right to free speech will not protect you. You may have the right to carry a firearm, (a very poor reading of the second amendment in my opinion and that's a whole different kettle of fish) a right the government cannot infringe, but your employer can, by denying you the right to remain employed while carrying a firearm on their property.
This is not a constitutional issue in any way, to imply it is shows a profound lack of understanding of the founders and the government they were trying to create. Go back and re-read the Federalist. You didn't understand Publius the first time through.
