(Cyber)bullying can become a serious burden for children and young people. Often, those affected do not manage to free themselves from such a psychologically stressful situation without help. Especially in the context of schools, the question therefore often arises as to how professionals can deal with bullying, both preventively and actively, when cases of bullying occur. The klicksafe teachers' handbook "What to do in case of (cyber)bullying?" offers basic information, suggestions for practice and introduces systemic conflict management. In March, klicksafe offers two modules on the topic of bullying as a full-day online training together with the participating authors Thomas Grüner and Jürgen Schmidt. Please note: unfortunately both dates in March are already fully booked!
