Any form of hostility (Krahe , 2001

Any form of hostility (Krahe , 2001:124) , as well as ganging (De Wet , 2011:67 ; Tehrani , 2004:191) , is seen as aggression. When it comes to undermining , the aggressor sometimes has the motive to block the victim's promotion (Krahe , 2001:123). The participants experienced aggression in the form of hostility when their successes were acknowledged (De Wet , 2011:57 ; Krahe , 2001:123). Often it is the best female teachers , rather than the weakest , who become victims of aggression (Wiedmer , 2011:36). The improvement of qualifications often results in aggression (Botha , 2008:207). This research identified the experience of a lack of recognition as prominent.
