I don't do pot, drink, or do drugs, ever. But I was fired for testing positive. When I tried to figure out how it happened, I was lied to, ignored, sent forged documents, etc.
I have a right under the constitution to be free from unreasonable searches. The S.C. decided that mandatory testing of employees working in safety-sensitive positions was a "search" under the constitution. If I am covered by mandate, the D.O.T. demands that my selection to undergo random testing must be truly random, verifiable scientifically. If an employer selects a worker to be tested, and pretends that he was chosen at random, the S.C. draws the line, and calls that a violation of this right.
But, there is no accountability within this system. The private testing businesses have become extremely profitable, enjoying the same bed as government officials. This information is on the net.
It appears to some, me included, that the influence of money's power, wins.
