Not sarcastic. I won’t hire smokers, period. If any worked for me, I find way to get rid of them. The first is perfectly legal, the second is debateable but as I am in a Right to Work state, doubt anyone could complain. Smoking is toxic and I want nothing to do with it. You want to smoke, find work elsewhere. Very simple, very direct. No sarcasm intended or needed.
I don’t want a nurse caring for me that has to “pop out” every half out to engage in the habit. My life is in her hands and not really sure if people having serious nicotine fits can be trusted to make rational life saving decisions.
