What Does It Mean to Be on Team Human?

In a world inundated with technology, it’s good to remember that being human is a team sport. We are literally all in this together.

For us, being on Team Human means putting people over profit in how we manage our business and our team. It means remembering the person on the other end of every email or screen share.

On a larger scale, it also means supporting privacy rights and resisting the so-called “attention economy” that has a divisive and isolating effect on us. It means that all people are equal, but we recognize the biases embedded in our cultural operating system that provide advantages for some groups over others. We strive to create a positive work environment where all employees can reach their full potential and maximize their contributions.

How We Give Back

Every business has a responsibility to participate in the communities it touches. For us, that means supporting local organizations working on access to food, improving access to education, the arts and supporting our veteran community. Our favorite organizations doing this work include the Arlington Food Assistance Center, Change Is Simple, LEAP for Education, and Salem Arts Festival.

From our Arlington-based office, we support the Arlington Food Assistance Center, which provides dignified access to over 80,000 pounds of food to nearly 2,400 families in need each week since 1988. Supplemental groceries from AFAC mean that families can remain in their homes, workers can stay on the job, children are ready to learn, and mothers and babies have the nutrition they need.

To support our industry, we recognize the military veterans who have served their country. Each year, the C3 team participates in Wreaths Across America, an annual day of service in which volunteers lay wreaths on thousands of veteran’s graves at Arlington National Cemetery as well as at more than 1,400 additional locations across the country.

Diversity Statement

As C3 grows as an organization, we are likewise committed to scaling our diversity, equity, and inclusion initiatives to ensure a robust and diverse talent pool to support our clients. In addition to our attraction strategies for new talent, we work hard to create a work environment in which our team members want to stay. To support this, we build diversity, equity, and inclusion capabilities among all C3 team members.

Through our diversity, equity, and inclusion policy, C3 is committed to creating an environment where all employees can reach their full potential and maximize their contributions. We are committed to our employees’ dignity and well-being and strive to create a place where all members of our team can grow both personally and professionally.
