      Pros

      Got a position relatively quickly.

      Cons

      System One is trying to pull a fast one on their contractors at Pepco Holding, they are in breach of contract. System One is illegally taking away contractually agreed to per diem, reducing our pay rates, and refusing to pay time and a half for over time. Do not work with System One and do not work with Pepco Holdings. They are shady and can not be trusted.

      Pros

      I was employed two weeks.

      Cons

      Everything I was told to get me to drop life and head halfway across the continent was a lie. The job duties were supervisory, but I was immediately deskilled to technician, then within two weeks I was liquidated. My job duties were lies. The duration of my contract were lies. The possibility of other contracts after this first one ended were lies. I knew I was only a temporary worker, but this was absolutely unconscionable
