Violence against teachers has reached unparallelled levels in recent years. The American Psychological Association Task Force on Violence Directed Against Teachers conducted a national study in 2011. Out of 2,998 teachers surveyed, 80 percent had been victimized in the workplace. In the city of Baltimore alone, school employees filed more than 300 injury claims related to student assaults in 2013. The only city agency that filed more claims was the police department. Teachers have the right to a safe workplace, which includes being free from student harassment, threats and attacks.
