This article, using data from a year-long study of writing processes in an institutional context, looks at the demands made on writers in workplace environments as they make requests of their colleagues. Building on Brown and Levinson's politeness theory, the study takes a view of context as being a key factor in framing requests, in addition subscribing to the notion of context as an ongoing dynamic, or mutually constitutive activity system. Although the variables of relative power and degree of imposition are important factors in the choices writers make, a further consideration is the need to balance their own relational needs with the expectations of the institution as they create texts for multiple audiences. In addition, the linguistic choices writers make in such contexts as they position themselves in relation to their peers and those further up the hierarchy may also serve to define and reinforce their identity within the institution.
