They are private employers. It's my business, my place of work. If I'm an employer and something you do in your private life may affect how you do your job, the cost I pay for health care benefits, and so forth, I give you the option. Take the drug test . . . or find work elsewhere. You don't have a right to work for me. You don't have a right to work for anybody other than yourself.
In particular, if you're diving a forklift for me or another motorized vehicle, or treating a patient for me or prioritizing patients for treatment, or writing a legal opinion that's backed by my malpractice coverage (and next year's premiums are going to be affected by your work) . . . or if I just don't like drugs . . . or for any other reason that's not illegal under the Constitution or applicable law? If I make a drug test part of the condition of employment, they you have the choice. Work for me and take the test or work elsewhere.
You don't have a Constitutional right to work for me.
You are absolutely correct I do not have that right and neither do you as an employer. I do not believe Government should ban it either, they have already done enough.
But regarding your views on drugs, maybe you could clarify a little. Is there a list of “Good Drugs” and “ Bad Drugs” you go by?? Is it “ ALL DRUGS” regardless of their nature? would it include or be limited to “ Any Mood Altering Substance” ???. Or is your thought limited to just “Illegal Drugs”. Now think carefully before answering and remember there is NO SUCH THING AS AN ILLEGAL DRUG, there are only “ Controlled Substances” which the Government has Decided you need SPECIAL PERMISSION FOR.
I await your response.
