Abstract
This study examined the level of collaboration between senior and junior academic staff in Higher Education Institutions in the Amhara Regional State, Ethiopia. We employed a convergent parallel mixed research design and collected data from 203 teachers, four department heads, and four academic deans using questionnaires and semi-structured interviews. The researchers also employed frequencies, percentages, mean, standard deviations, independent sample t-test, and one-way analysis on variance to analyze and interpret the quantitative data. The qualitative data on the other hand, was analyzed thematically using reflexive thematic analysis. The results show that the collaboration between senior and junior faculty members is too weak and limited to information exchange and material-sharing practices. The study also shows that independent variables such as gender and level of qualification did not affect senior and junior staff collaboration, while age and teaching experience affected it. We recommend the concerned bodies in higher education institutions to establish a system that entertains a genuine collaborative culture between senior and junior academic staff, following an integrative approach among different groups and considering all the challenges in realizing such an effective collaboration.
