How does hiring of policy professionals, to do the policy work of civil society organizations, impact the organizations that hire them? Policy professionals constitute a growing group of actors who populate many interest groups, working with advocacy and influencing public policy. As a group they comprise various types of professionals, displaying different backgrounds, identities and motivations. By analyzing individual policy professionals, asking questions about their identity and motivation to work with advocacy, and then through ethnographical observations following their work, this article contributes to the understanding of how policy professionals’ backgrounds and professional identities are connected to organizational strategies and the process of professionalization. In so doing, it sheds new light on the dynamics of policy production and what professionalization of politics looks like in civil society. The article proposes a categorization of policy professionals’ role orientations in civil society as policy scholars, policy lobbyists, policy communicators and policy activists. This conceptualization is of analytical value, because the balance between these categories affects dynamics within organizations and the work they do in relation to advocacy and policy, in tandem with their legitimacy.
