Employee Resource Groups
As a highly connected global company that is Leading with Science®, Tetra Tech embraces the diversity of thought and experience that is integral to creating innovative solutions.
Our global Employee Resource Groups (ERGs) help us attract and retain the best engineers, technical specialists, and support staff from diverse backgrounds. These voluntary ERG networks support the professional development and inclusion of employees with shared characteristics, special interests, or life experiences.
Our Diversity, Equity & Inclusion (DEI) Council guides and charters our ERGs, which focus on topics including business development, mentoring and requesting feedback, prioritizing and delegating, addressing harassment, and improving business communication techniques. ERG Sponsors participate on the DEI Council with our executive leadership team to provide input on the direction of the company’s DEI programming.
Each global ERG is open to all and involves activities for both employees whose background is the focus of the ERG and other employees who are supportive of the group (also known as allies).
ERGs support our thriving, global employee community
Tetra Tech has chartered the following ERGs, and our DEI Council is working with other groups across the company that are on the path to global charter or that serve specific local needs.
