      Pros

      There are good operating units under the Tetra Tech Umbrella

      Cons

      EMI & TDR. They are known for violating labor laws. They’ll pocket your per diem & give you less than the GSA rate. Expect to work 60-80 hrs / week or not at all. Seriously incompetent management, understandable as those are the only people left after quality individuals leave for better companies.
