Oh boy.
What about people who work there, smoke, but have insurance through their spouses employer?
Or what about people who work there, don't smoke, but the spouses do?
What about family coverage where a teenager smokes without permission? Fire the Dad or Mom?
Can of worms people. Keep the powers that be out of our lives, or next they'll come for you.
BTW, my wife and I quit smoking in 1988, in case any wonders.
The can of worms was opened when companies starting paying for health insurance. That is what has created all this.
If your employer paid your auto insurance, they would dictate what type of car you would drive.
The problem is not that the company is over-reaching, but that the employees want benefits without any strings.
