ABSTRACTTo gain support for their programs, mission, and aims, organizations engage in identity work to establish and communicate who and what an organization is. We argue that identity work is a core strategic communication effort, and furthermore that rhetoric is central to the process. To better understand such identity work, we engage in a case study of an emerging organizational form, social entrepreneurship (SE), by analyzing the identity rhetoric of three large SE umbrella organizations (Ashoka, The Skoll Foundation, Echoing Green). We find that SE identity work is constructed at both the organizational level and at the level of SE as a whole field or sector. Our contributions highlight the tensions brought about in communicatively constructing identity at multiple levels, and the need for further strategic communication scholarship that critiques identity work as arguments for a vision for social change agendas.
