Boy, am I glad that you can see the point I was trying to make. I always wonder if I am just incredibly unclear or what when I have problems with someone I am discussing matters with.
There is a fundamental trouble I have with the view of those that believe it is acceptable for an employer to make smoking a condition of employment.
Smoking is simply one of many, legal, private behaviors that are simply nobody's business. Whether I engage in anal sex, football or skydiving is none of your business and whether you engage in these activities is none of my business.
Allowing employers to require employees to submit to tests to determine if they are engaging in legal behaviors is to give way too much power to the employer.
I do support the employer being able to govern what takes place on his own property or what the employee does while on company time.
That is where the employer's rights end and the individuals begin. If I am not on the employer's time or property I want to know where the employer gets the right to to regulate my private, legal behavior or subject me to tests as a condition of employment.
Generally this kind of behavior would be viewed as unreasonable. It only becomes reasonable when done to smokers because there is a lot of intolerance toward smokers. If we did it to other people for other behaviors there would be public outrage.
