middle and lower management great, upper management terrible - Electrical Technician WesTech Engineering Employee Review

Upper management lies about policy, and creates policy changes out of nowhere. HR isn't there for the employee's - basically received no support or help from them when being terminated over a false positive on a drug test. Requested a retest and was told policy didn't allow it, yet our employee handbook clearly stated that it WAS allowed and up to management. Was told I was re-hirable in my exit interview, as long as I could pass my drug screening (which I could) but then was told 2 weeks later that they changed policy, and I now needed to wait a year to be rehired. Devoted 7 years to this company, was never written up, had no accidents or incidents but was let go with no chance or opportunity to prove my innocence.
