The research presented here seeks to understand a phenomenon that is concealed in the daily conflicts that afflict the school institution: the mistreatment experienced by teachers at the hands of their students which, like other manifestations of violence, can be camouflaged, take the appearance of a game, or of simple deviations that in the collective imaginary do not generate major consequences. Mistreatment is defined as the consequence of daily interactions in which aggression is used as a mechanism to impose particular points of view and interests, which are based on social meanings that affect the positioning with respect to the reference group in the case of the agent of mistreatment.
