Background <p>Experiences of violence against their person affect teachers′ health, wellbeing, and professional performance. Until now, there has been no comprehensive, systematic analysis of violence against teachers, its effects, and the support systems available in German-speaking Switzerland.</p> Methods <p>This study represents a&#xa0;quantitative and exploratory investigation based on a&#xa0;representative online survey conducted in 2022. It focuses on a&#xa0;detailed description of the most serious experience of violence within the past 5&#xa0;years by 5435&#xa0;teachers of all school levels in German-speaking Switzerland. The analysis examined the prevalence of psychological and physical violence, the reactions of those affected, the consequences of the incidents, and the perceived obstacles to coping.</p> Results <p>Two thirds of teachers had experienced at least one form of violence in the past five school years. In the most serious cases described, 38% of those affected reported long-term mental and emotional stress. The effects increase significantly when the violence is perpetrated by superiors (school management) or colleagues. Only around half of the teachers who sought help felt well supported by the school management. The school management was cited by 20% of those affected as the biggest obstacle to dealing with the incidents.</p> Conclusion <p>The findings show that experiences of violence have serious consequences for those affected and that structural deficits are evident throughout the chain of prevention, intervention, and aftercare. In view of the legal and organizational obligation of school administrators and school authorities to protect the health of teachers, there is an urgent need for action. The study recommends implementation of a&#xa0;school-wide, data-driven, and independent support architecture, including low-threshold contact points such as ombudsman offices, to reduce power asymmetries and improve access to adequate help.</p>
