what's the specific policy on weapons in the workplace? obviously firearms are a total no-go, but what about a pocket knife? is there a specific blade length that would be allowable? i ask because i've had a few totally insane drivers harass me for driving the speed limit after i leave my facility, including one that tried to force my vehicle to stop so he could presumably "teach me a lesson" or something, and if i can't have a firearm on company policy, it would be nice to have SOMETHING to defend myself with. even Federal facilities allows a 2.5in blade, what about UPS?
