how about you carry at work and DO NOT have an ND or allow anyone to know your carrying. you have a job that you love and co-workers that are like family. You feel threatened enough about this "guy" to hit the boards on a gun forum of all places and ask advice about your personal safety. If I really cared about my co-workers and had a real gut feeling of a threat of violence against one of them or myself, I would carry a firearm. Are you telling me you cannot make it a week at work without guaranteeing that you won't have an ND? Whatever man, it's you life and your friends. I am sure it's nothing and life will go on, but if that's not the case, who knows what could happen to the lives and family's of these people you "care" about. Obviously, you only care enough to CYA and keep your job and hope someone else has the testicular fortitude and tools available if real action needs to be taken.
I love the comment about the restraining order, if he is intent on harming anyone in your company, that'll be just as useful and the "gun free" zone in Newtown, Conn.
If your work attire is professional, then you have some of the best options for carry modes. If it's dress casual, you may need to wear a button up with a under-shoulder. if it's tucked polo and you absolutely cannot be seen with a weapon, then you may need to make the small investment in a pistol suitable for ankle carry. I o agree though, that if you work in a government building/building with detectors than don't carry, but those places have armed guards anyhow so there WILL be a "good guy with a gun" if the need arises, no need for you to be that "good guy" if you have guards that are being paid for the pleasure. My job forbids carry and then sends us into the worst ghettos of downtown Atlanta with a truck that everyone knows has narcotics on it. I like my job, I love my partner, we have become family over the years and we have both agreed to get our permits and carry and keep it to ourselves.....why? because we both have a wife and young child to come home to. Lucky for us, we have not needed to use/brandish/draw our weapon on the job, but neither of us would hesitate even though it may be the end of several years of schooling and licensing. Would I be 100% surely canned if we protected ourselves, I am not sure, my bosses/owner seem to have at least one foot in the real world and understands what we are up against and our governor had the good sense to allow EMS/FIRE to carry as of this year, used to be illegal since they are technically on government property, GO NATHAN DEAL(this gov has stood up for our rights in so many instances it's unreal). although we are not police, it's not a stretch that someone would target any city worker in todays climate. Someone set his house on fire a couple years back, called 911, waited for the truck to arrive and ambushed them with semi-auto rifle fire. I don't like my job enough to die for it, I am not a soldier and shouldn't need to give up my constitutional rights of protection so my bosses can save a little coin on insurance/lawsuits.
From what we have heard, this guy probably isn't going to walk in with AK's blazing laying ruins to your beloved job. But I can say if my gut thought something was off and any possibility of armed violence could occur, I could find a place to carry a firearm and I could absolutely avoid an ND for a couple of days
. My .2c, obviously not on the same page as your thinking, so I wish you well and hope that this boils over and it's not someone you don't expect that snaps one day and wishes to bring violence upon your family of co-workers. This is just one guy and one incident, that you happened to be involved with, you never know who or what is going to happen at anywhere at any moment. Figure out for yourself if a company wide-email holds the same value as human life should an incident take place. obviously disregard everything I said if your work place has actual state/fed law forbidding carry, I am not condoning that, but that doesn't sound like it's the case anyway. good luck, stay safe and remember that you don't have to be the sheep or bow to rules that endanger your livelihood just because your boss/whoever has a wad over firearms, you can keep it discreet and keep it your dirty little secret, and i'll bet if it is ever needed and you save the lives of your co-workers and subsequently lose your job, your co-workers aren't going to stand idly by while you and your family starve after saving all their hides.
