Pros

As long as you are billable and meeting project deadlines/responsibilities, you are set and will have a lot of flexibility (i.e. working from home) and on your own schedule. Over the years, I have done a variety of office and field projects, and feel this has given me greater perspective on the environmental industry. Tetra Tech does perform a lot of different types of work.

Cons

When work slows down, a lot of onus is placed on the employee to find their own work and maintain utilization. Heavy emphasis on utilization. The down-side of this is that in any given year, your most important goal will likely be to remain highly billable and/or bring in work. You will likely get stuck doing mundane work to meet utilization requirements. Training/mentorship and employee development is not a priority. Doing good or even excellent work on assignments is not enough to significantly advance your career.

Ability to work across department lines.

Cons

Discriminatory practices destroyed department moral. Voicing concerns became grounds for retaliation. No assistance from higher-ups when reported.
