Do the security guards at airports have to go through airport security when they get to work?

No,they don't.Because they ARE airport Security.and they're authorized to carry handguns so what use would it be to scan them?

I'm not sure if they do или not, I'd imagine not. I know they let employees that work beyond the security check point go through without getting checked, but they make pilots and flight attendants go through security.

i have no idea. Maybe
