No, but it may prevent them from adequately helping someone who needs it. Is it fair that a child with asthma or a pregnant woman/preemie baby have to be exposed to someone's third-hand smoke? Just because they aren't smoking around them doesn't mean anything. If they want to smoke while they're not at work, that's fine, whatever. But wearing your scrubs and taking a smoke break while you're at work seems hazardous, reckless, and shows a potential lack of respect to the patients you have to care for. I realize this may be blowing it out of proportion to some people, but cigarettes are a touchy subject with me.
I know it is I don't disagree with you either. Our local hospital district has a no smoking policy at all of its buildings. I think that's a good thing.
Maybe I read it wrong, but I thought they were refusing to hire people that smoked period, which would be discriminatory.
