Online work distribution platforms such as *Amazon Mechanical Turk* or *Uber* alter how work tasks are chosen or assigned. Put succinctly, instead of the employer choosing the employee, the worker chooses the task. Responses to these new technological possibilities for distributing tasks are all deeply influenced by the contemporary historical moment, which privileges approaches to workers that take them to be neoliberal market actors. In this article, we examine how these platforms interact with current ideas about work and contemporary configurations of work by altering the ways work is accomplished both within and outside of an organization through open calls. In particular, we focus on the challenges these platforms bring to the problems of coordination ever-present in any project of designing the work, disseminating the work, and controlling the work process.
