Silence is traditionally understood as a power deficit; yet, it creates spaces in which power works unobtrusively. In this article, I report the findings of a qualitative study examining silence in school relationships. Based on nine conceptual discussions and 33 interviews with teachers and students in a secondary school in the UK, I assert that uses of silence in relationships between students and teachers revolve around two conceptions of power: a stronghold of respect and a refuge for dignity.
