Time for you to pony up.
Your choices are; work a dangerous job where there is a good chance you will be attacked by a criminal. You can't quit (or if you do your family will suffer great deprivation) and your company will not allow CCW. Do you not carry and face the strong possibility of being killed or injured by a criminal? Or do you carry anyway and face being fired?
