This article applies identity construction concepts to a professional and technical communication student intern's use of agency as she negotiates a unique identity for herself within a state legislature. Following a literature review, the author highlights several of the intern's key efforts to become part of this new governmental and legal discourse community, including learning legislature-specific genres, combatting the "totem-pole" hierarchy, making choices about appropriate professional behavior, socializing by creating an "entire family dynamic," and making an effort to learn the culture of the legislature. These efforts are documented through the intern's reflective, self-narratives and documents produced during the internship. Through this discussion, the author suggests practical implications for aiding students and newcomers as they transition to unfamiliar workplace communication environments.
