I work at a hospital, and there is a no weapons policy at my facility, which includes knives. Quite frankly, I'd be incredibly surprised if any hospital allowed weapons on premises outside of site security, DOC, and the police. A hospital is a place where people go to get healed, and this view informs the entire operation of every facility, as it also leads to federal dollars paying the bills in a very direct way. And you know how much businesses love their federal dollars.
Our facility has terminated employees with extreme prejudice (i.e., instant termination and dismissal) for violation of the no weapons policy, including CCW license holders. That should set the bar for you, a bit.
