I'm in the same predicament -- My employer has big "No weapons or firearms allowed" in the entrances of my job so I can lose my job if I decide to carry at work and someone found out.
So I just leave my cc weapon in my car parked in the garage. It really puts us employees at a huge disadvantage not having our cc weapons on us. We already had a shooting where an employee was gunned down and killed in the parking lot. If that person was able to carry at work, he would've had a chance to defend himself from the BG.
