Would you ccw at work?

that is if it was against company policy? I work in retail and it's against company policy to carry a concealed firearm. I have my cwl and after a convo with my co worker I found out he carries his glock26 in a iwb at work everyday. My store has gotten robbed before. I have a glock 27 which conceales extreamly well in my iwb.. I wouldn't even worry about a chance of anyone noticing it. I am thinking about starting to wear it while I'm working. I personally would rather get fired then get killed. Y'all got any opinions on this?
