Hey! They can pick and choose whomever they want to hire. But they should have set down ground rules before they started the hiring process. Changing rules in midstream is not right. What choice do these people have now? They are being forced into something they do not want, and it's just going to add to more misery or hating to go to work.
They are going to sneak cigarettes in places that might not be in a safe area. I think it's terrible.
Also, what about the Anti-Discrimination Act? This is discrimination.
I suggest smokers form their own home project/improvement chain and make it a foundational company policy that employees are allowed to smoke anywhere, at anytime, and for as long as they want. Let's call the chain "The Duke's Home Improvement" in honor of the legendary one-lunged chain-smoking John Wayne.
Quit whining and win this fight the American way.
