The The Academic Staff Union of Universities (ASUU) is opposing a bill aimed at preventing sexual harassment at universities.
The union says the law unduly targets and stigmatises university lecturers.
The bill is suggesting a five-year jail term for lecturers convicted of sexual harassment of their students.
The bill was introduced following the BBC Africa Eye investigation which exposed sexual misconduct by multiple lecturers at two top West African universities.
The revelations led to the suspension of some lecturers at both the University of Lagos and the University of Ghana.
