Is there any kind of privacy laws associated with drug testing? I tested positive on a drug screen at work and was able to retest and passed the second one. While waiting the results I was not able to return to work, during this time the news got out that I tested positive and now my entire office knows about it. I thought that the results were completely confidential. The only people that knew were the supervisors and the head of hr. I want to know if I might have a legal case against them for slander or something similar. Any help would be great.
