I am a smoker, yet still productive. While all the fat cows...err...obese employees are grazing....err snacking in the cafe, I am out behind the hospital, in a tinted "cage", smoking.
I agree once they ban it, employees will smoke anywhere, all ashtrays have been gotten rid of, therefore there's going to be cigarette butts all over the place.
I think it's one thing to be able to control what happens at the workplace, hence making a smoking ban. But attempting to control what happens at home, hence testing for nicotine in the urine.....ridiculous!
