I’m wondering if that Doctor that shot the murderer this week will get fired. He had concealed carry and saved lives but...
While that hospital might have a policy of forbidding firearms, I doubt that the hospital's insurance specifically forbids employees from carrying firearms or resisting attacks. So the hospital board of directors might be able to say, "We do have a no-gun policy, but we're not going to enforce it this time." without violating any contracts.
Just guesses.
