Pros

None that I can think of.

Cons

Terrible leave policy, and at many subsidiaries you will have the "option" of applying leave to your timesheet to reach 40 hours, which is almost every week. (As a result you will rarely be able to take an actual day off because most of your leave will go toward simply getting a paycheck.) No opportunity for professional growth or advancement, and Tetra Tech is really just a big holding company, so if your division gets slow you will be laid off (or "reduced in status," which is to say made part time involuntarily, as I was) rather than transferred to another division with more work.
