My experience in trying to obtain a job at LabCorp has to be the worst experience I have ever had with a company. From the time I first applied on their website (for 3 similar positions, each with a different starting and end time for work) until the day I was to begin employment took nearly two months. First I was sent an email saying that the position I had applied for was cancelled (not specifying exactly WHICH position was cancelled, as I had applied to more than one). In the meantime, I took an interim job elsewhere to bring in money. About a month and a half after first applying, I get another email from someone in HR saying that had an update on my application and they wanted to make me an offer. I accepted the offer and completed their time consuming online onboarding paperwork. I had to agree to take a drug screening and consent to a background check as conditions of my job offer, which I did. Here is where things fell apart. I have been taking drug tests regularly as part of my job between 1992 and 2014 without any problems. Since I've never used drugs (and never will), I always passed any drug test I was given. But, when I called to get the results of my drug test for LabCorp, I was told that I tested positive for codeine. This is not possible, since I am not taking any prescription drugs at all and have nothing in the house that contains codeine. I reported the results of the drug test to HR as requested, but had to leave a voicemail message since no one answered the phone when I called. I also left a message with the person who was to be my supervisor at the new job, and sent an email to HR and the local LabCorp office where I'd be working about the drug test results. Not ONE person at LabCorp responded to any of my phone calls or emails after I told them the results of my drug test. Suddenly I had gone from someone that in the words of their offer letter "would be a strong addition to the team" and who they had confidence in long-term success at the company, to an apparent substance abuser that the company wanted nothing to do with. For someone who has never used any illegal drugs in his entire life to be treated this way is completely unacceptable, especially from a company as large as LabCorp. I expected much more professionalism and decency than I was given from this company. This should be a lesson to anyone thinking about applying for work with this company. If a person who has always been law-abiding and lived a clean and sober life, without the influence of illegal drugs can be suspected of using a controlled substance as a result of a pre-employment drug test, and then had a job offer rescinded as a result of an inaccurate test, then this could happen to ANYONE. Do you really want to work for a company that is willing to treat you like a criminal when you've done absolutely nothing wrong?
