Organisation theory mobilises fundamental notions such as the individual in order to understand and explain the organisational phenomena it studies. However, this mobilisation is sometimes done without ever proceeding to a radical critical work in the Nietzschean sense of the foundations of this notion. By using the Nietzschean conception of the individual, the objective of this paper is precisely to expose the unthinkings that underlie the notion of the individual in order to draw out the contributions and implications for organisation theory. In this paper, we argue that the Nietzschean critique of the individual is an invitation for organisation theory research to consider every individual as embodying a plural identity.
