Cleveland Clinic Will No Longer Hire Smokers

My thoughts on the policy of The Cleveland Clinic (and many other companies) not to hire smokers. It is, pure and simple, a form of discrimination!
They are not allowed (by law) to discriminate against anyone based on their age, sex, religion, or disability. They should not be able to dictate what an employee can do on their own personal free time, especially if it is legal! Unless a persons' private life (if they smoke, drink beer, etc.) disrupts their performance at work, they should be allowed to participate in any legal acivity that they want to! Sure, an employer can dictate that its' employees cannot drink or smoke at work (duh), but what an employee does with their free time is their own business.
If the employer is concerned about increased health insurance costs for smokers, then they can pass the additional cost on to the smoker and let the employee decide if they want to quit smoking and save themselves the extra money.
What is next?
You're overweight, and if you don't lose the extra weight and get healthy, we will have to get rid of you. We will not hire any overweight people because they have more health problems. We will give you a list of required foods that you can eat to remain healthy, and if we catch you eating anything that is not on our list, you will be let go...
We looked at your driving record, and noticed that you have quite a few speeding tickets. You are at a greater risk, because of this, to suffer injury and miss time from work. Therefore, if you get another speeding ticket, we will have to find a safer driver...
We don't think that people that go deer hunting should work for our company...
A recent study found that women that shave their legs are more prone to infections from razor cuts, therefore, shaving your legs will no longer be tolerated...
If you have more than one child, you are considered to have added stress. Therefore new company policy dictates that you must get sterilized after your first child...
Can you see my point?
