Mobbing is an antagonistic behavior with unethical communication directed systematically at one
individual by one or more persons in the workplace. This study aims to identify the mobbing behaviors against
demonstrators and assistant lecturers working at Assiut University. A cross-sectional descriptive survey was used in
this study. The current study was conducted at six faculties, i.e. the Faculties of Commerce, Social Work, Law,
Engineering, Nursing and Medicine. A stratified random sample technique was used on (535) demonstrators and
assistant lecturers. A self-administered questionnaire was used to collect data which included socio-demographic
data and the mobbing behavior questionnaire. The main results of this study indicated that 57.9 % of the participants
were females and 42.1% were males. The main type of types of mobbing behaviors against demonstrators and
assistant lecturers was attacks on their professional status (53.7% and 44.3%, respectively). 49.6% of demonstrators
and 43.4% of assistant lecturers responded psychosocially to mobbing behaviors. Thesis supervisors and
departmental heads (18.7% and 18.1%, respectively) considered the main sources of mobbing behaviors against the
studied participants. This study recommended that an educational program should be applied to managers,
demonstrators and assistant lecturers working at Assiut University about the advantage of the open managerial
