My workplace has an official company policy of no weapons of any kind in the office. And there is no security. Nada.
Some psycho with a Mossberg pump could just walk through the front door and really ruin a lot of weekends for a lot of families.
However, the “lunch” I carry to work every day is very, very high in minerals. Very.
I salute your bravery. Someday you may be a hero to some kid whose father or mother makes it home instead of being killed by a thug. (You might also get fired, but I get the feeling that wouldn’t be the end of the world for you.)
