This article presents findings from a documentary analysis of 300 disciplinary orders against teachers from the General Teaching Council (GTC) for England. While the extant literature concerning teacher misbehaviour focuses primarily on pedagogical practice, this article draws on the wider organisational misbehaviour paradigm and views teachers as professional employees rather than just classroom practitioners. As such, teachers are embedded within the complexity of organisational systems, procedures and interrelationships as well as being regulated by professional standards. The analysis found that teachers were disciplined for misbehaviours both internal to the employing school and also activities, primarily criminal, that were external to their employment. The article argues that the professional regulation of teaching, being accountable inside and outside of work and the emotional labour of teaching should define teacher misbehaviour as separate from generic organisational misbehaviour frameworks. Furthermore, it argues that, while the GTC viewed teacher misbehaviour as a product of the individual, organisational contexts are also important antecedents of activities that are considered deviant.
