I agree with killerweed420, if the test really was "inconclusive", and I have never heard of an inconclusive test out of the millions of results I dealt with on a daily basis for nearly 2 years, they would let you retest. Failing a drug test is kind of a big thing because most places bar you from employment for a year, they have an MRO doctor call you to talk about when you last used the drug you tested positive for, etc. so a failed test not something they are going to just drop on you without any further explanation. THey have strict regulations they must follow with failed tests. Sounds like they were just trying to cut you out without laying you off, probably to try to get out of paying unemployment or something.
