No. If a person does the job to the employers satisfaction it should not matter whether they smoke or not.
Every non-smoker has to put up with the lousy productivity of the smoker going outside to smoke and letting someone else do the work.
You have now fallen into the trap of generalization. Many many other things can cause lousy productivity.
In addition, smokers are absent more often and for longer periods of time, on average, than non-smokers.
Another piece of anti bull. If a smoker is healthy to begin with and takes care of themselves they miss no more work than a nonsmoker.
Also, ever place I have worked, the smokers create huge "butt" mess in their smokng area.
Every place I've ever worked the people that eat fast food make a mess. I'm not going to demand that they pay extra to clean up that mess. I don't expect to be asked to pay extra when I DON'T make a mess.
Of course, smokers could demand a lower deduction for pensions since they, on average, will not be around as long to collect.
If we don't live as long then why are we being asked to support states budgets with cigarette taxes? We're not going to be around to enjoy whatever programs the state comes up with. Right?
If a bar owner should have the right to make his bar a smoking bar, then any other employer should also have the right to allow who he pleases on his property.
What's sauce for the goose is sauce for the gander.
