I don't even have my CHL yet, but I felt compelled to add my two cents here. Due to the sheep-like nature of many of our fellow citizens (this is sad, but true), I've already decided NOT to inform anyone that I work with that I hold a CHL or that I carry a firearm. There's simply too much disinformation and ignorance about guns out there right now...remember, "pick your battles."
The pervasive "culture of fear" has really taken it's toll on the common sense of contemporary Americans. For what it's worth, I'm an attorney by profession, but I currently teach law for a living. As such, I recommend that you exercise extreme discretion around the workplace, church, and other social/professional settings. At the very least, only mention the CHL/gun that you carry to others that you know are like-minded. One poorly informed fool who panics and blabs to your co-workers could seriously ruin your day, or worse!
