I carry except at work; they have a "no weapons" policy, usually interpeted to mean we've got to secure our sidearms in our cars. (No one has tried to test that one by asking -- why push it?). I'd guess a dozen of us carry.
However, the company does offer security services: the guard on duty will walk you to and from your car. As it's a smallish (250 +/-)staff with staggered working hours, and well-lit, fenced lots, that works out okay. (Downside, one of the parking lots is two blocks away from the building and has no human-presence security, only the fence. I won't park there). Plus I usually have a tool bag filled with interestingly dangerous things ready to hand.
As a practical matter, carrying inside the building would present problems: it's a small place, mazelike and densely "populated." Frangible rounds would be my choice and even then, I'd run rather than shoot if running was an option. I value my life -- and I value not having to spend months of it explaining how it was I shot a bad guy and half of the Art Department. Let the company's guard shoot 'em instead, he's insured for it.

"Hand me that 1911, I've found the problem...." H'mm, not a usual maintenance procedure for electronics. But in some cases?
