Awful - Senior Systems Administrator MANTECH Employee Review

I was treated horribly by Mantech. I was hired by one manager and then was fired by other for no good reason. I was fired for disagreeing with him. He said I was disrespectful and instead of HR even asking for my version of events or giving me a warning, I was let go. They totally humiliated me. I have never been fired before and have went onto better companies. Be very wary of this company and avoid them at all costs.
