We had a CFO bring a handgun onto company property in his car. Some one spotted it (apparently, it was in plain view in the car) and notified the police. He was given a talking-to by the cops and then by company reps. He wasn't fired at that point but he was gone in a month or two. Related? I don't know but it wouldn't surprise me.

The company is in Sunnyvale, site of the Richard Farley murders at ESL in 1988. So, yeah, I think the police would be interested in knowing his intentions.

In areas of the country where some material number of people do carry firearms (e.g. Texas), it's not uncommon to have explicit signs on company buildings that forbid firearms. I imagine that's pretty common policy at many if not most companies.

Though unless they have metal detectors, it's a bit like requiring your employees to wear briefs.

If you can tell they're not doing what you say, they're not doing it right.

Depends. There are open carry and concealed carry licenses. Also, if you are an employee and sneak a weapon in and someone finds out, you will be fired.

Why? If you were worth hundreds of millions, wouldn't it make sense to have some means of self defense?

Sure, I'm just saying that I would expect some people to take issue if I did.
