If where you work is that bad, the question should be who's hiring.
Where I work isn't bad at all actually. I thought the entire premise of concealed carry was to be prepared at any time. Well, I spent the majority of my time (that I am awake anyway) at work. As I said, I also think that statistically this is the biggest day to day risk to me because I deal with hundreds of unknown members of the public (aka customers) each day. In my neighborhood, at the park, etc. I don't encounter nearly the number of people as I do during a day of work - every day. I feel that, statistically speaking, if something was going to happen to me that required the protection of a weapon, chances are overwhelming that it would be while I was at work, where policy states I am not allowed to have a weapon!
