The definition of mobbing reads: “Psychological terror or mobbing in the workplace involves hostile and unethical communication, which is systematically directed by one or more individuals, mainly to one individual, who has been pushed to a helpless position without defence and held in it through constant mobilizing activities. These activities take place with high frequency and over a longer period. Due to the high frequency and long duration of hostile behaviour, it leads to significant mental, psychosomatic and social suffering". Mobbing as a form of workplace violence Leymann has divided it into 45 forms in which it can occur. According to the method of violence, we divide into: physical, verbal, psychological and sexual. Nurses and technicians in the workplace are exposed to violence by patients, their families or guardians, companions and associates regardless of profession. Mobbing can have different consequences on psycho-physiological balance, social-emotional balance, behaviour and on the work organization itself. Prevention is required at three levels: primary, secondary and tertiary. The purpose of this paper was to examine how much and to what extent nurses were exposed to violence at the Emergency Admissions Departments and Institutes of Emergency Medicine. The aim was also to find out if the violence had an impact on their work and whether the nurses felt safe in their workplace. The institutions that were involved in the research are: County Hospital Čakovec in Department of Emergency Medicine, County Hospital Koprivnica in Department of Emergency Medicine, Institute of Emergency Medicine Koprivničko-križevačka county, Institute of Emergency Medicine Varaždinska county and Institute of Emergency Medicine Međimurska county. The results obtained were compared with other studies from Croatia and the world. The results of a survey by the Croatian Chamber of Nurses, from which questions were previously taken, were also compared. Almost in every question, both studies are coinciding. Research has shown that almost all respondents were exposed to violence, and most of them were exposed to verbal violence. Very few of those who have been exposed to sexual violence, but by no means negligible.
