Teaching profession at all levels is presumed to be a noble one world-wide. It remains a profession that sees to both behavioural and mental development of any individual. Therefore, the role of a teacher in every society is very paramount. More importantly, all facets of a country's life depend on manpower produced from various tertiary institutions. Presently in Nigerian tertiary education, this purpose has been undermined due to numerous unethical practices, especially among the academic staff. On this background, the paper discusses some unprofessional conducts among the Nigerian tertiary educators such as sexual harassment, forgery, plagiarism, extortion, etc. Using analytical research approach, Ike's The Naked Gods (2015), Coetzee's Disgrace (2000), Nwosu's Dogs in Ivory Tower (2004) and Adimora-Ezeigbo's Trafficked (2008) are selected for this study. The paper identifies production of numerous unemployable graduates as one of the side effects of all the aforementioned behaviours bedeviling Nigerian higher institutions of learning. The article concludes by emphasizing the need to rebuild trust and integrity in tertiary institutions in Nigeria.
