Professionalism in a field research community

At Tyson, we aim to foster a collegial, professional, and productive environment. To achieve this goal, we ask members of the Tyson community to be polite, responsible, and punctual, and to contribute meaningfully to the station at large. While our community climate appears to be somewhat casual, please always keep professionalism in mind.

Within the Tyson community there will be a wide variety of ages, ethnicities, socio-economic backgrounds, gender identifications, and religious or non-religious belief systems. Some differences may not be easily seen, and some individuals may not feel comfortable sharing that they are different from the majority. In order to foster an inclusive work environment, Tyson users are expected to be respectful of everyone, and to take steps to address any cultural insensitivity that you witness or hear about. You may speak directly with Kim Medley or Susan Flowers about concerns or use the anonymous comment boxes located in both Headquarters bathrooms.

We value the presence of researchers of all ages at Tyson, from pre-college youth to seasoned faculty. We appreciate your assistance in creating a welcoming field station community.
