“…In the United States, the most recent Indicators of School Crime and Safety Report showed that 5-10% of teachers reported being threatened with injury or physically attacked in the 2003/4 school year (Dinkes, Kemp, & Baum, 2009). However, there is little systematic evidence of these suppositions beyond isolated case studies, which have explored school principals' misuse of power against teachers (Blasé & Blasé, 2004) and teachers' experience of bullying by their principals (Fox & Stallworth, 2010). Most studies have focused on the immediate outcomes of student aggression (Espelage, Holt, & Henkel, 2003;Galand, Lecocq, & Philippot, 2007) while ignoring aggression against teachers by co-teachers, which could predict teacher aggression (Fox & Stallworth, 2010;Somech & Oplatka, 2009).…”
