This study examines the behavioural, individual and contextual variables that are expected to impact the perceived severity of workplace bullying behaviour. It also identifies the toxic behaviour involved in interacting with workplace bullying for the employees at AlHakim General Hospital in Iraq. Thus, to find the psychological symptoms associated with the related behaviours, the Brief Symptom Inventory (BSI) was used. Based on the analysis, the findings indicated that the severity and classification of workplace bullying behaviours had been influenced by the toxic behaviours involved through the characteristics of the employee who is subjected to those behaviours. The analysis conducted in this research also indicated that the behaviours that were personally harnessed from the corresponding target were more severe and frequent than other categories of behaviour. Finally, having an appropriate organisational system is of great importance to guarantee high performance in the organisation
