The article identifies some factors that made lecturers to leave the University of Zambia (UNZA) for alternative employment between 1990 to 2016. The aim of the study was to establish the reasons some of the lecturers decided to remain serving UNZA faithfully in spite of their friends leaving to alternative places that had attractive conditions of service. This study used mixed method approach. Convergent parallel mixed methods, which involved both quantitative and qualitative research methods were used. Quantitative data was analysed using statistical package for social sciences (SPSS). Qualitative data was analysed using common responses from themes. Research findings show that lecturers left UNZA because of poor economic conditions which prevailed in the country among other factors. The study conclude that too much of labour turnover can severely reduce productivity, as workers who are perpetual learners and new to the institution all the time demoralise incumbents and damage an institution's public image thereby adversely affecting its corporate existence. It is recommended that managers should be trained before they take up their offices. Retirement package and remunerations should be paid on time in order to motivate lecturers.
