This study explores the nature of work-related cyber mistreatment from guardians, pupils, and members of the public as experienced by educational workers. Thematic analysis of data collected by semi-structured interviews with 31 teachers and principals resulted in two overarching themes; directly addressed cyber mistreatment in email and unwanted negative exposure on social media. The data spans over different types of cyber mistreatment, ranging from cyber incivility to cyberaggression. Educational workers typically feel powerless when exposed to mistreatment, and require support to manage these complex, novel, and distressing situations.
