Pros of working at Tetra Tech

Tetra Tech's Corporate HQ in Pasadena provides excellent opportunities for motivated employees working elsewhere in the company to participate in development of new operating systems for the company and does an excellent job rewarding and recognizing employees who participate in in such special projects

Cons of working at Tetra Tech

It was my experience working at Tetra Tech that the hours were long due to inadequate staffing to properly perform one's responsibilities. Also, management of some Tetra Tech Operating demonstrate no loyalty to employees who work hard and perform well. They are quick to lay off employees and focus primarily on the bottom line and not on loyalty to excellent performing employees

Tetra Tech benefits

My favorite perk was being given the opportunity on several occassions to work on special Corporate HQ projects in addition to performance of my regular duties.
