The Union of Students in Ireland says it is concerned at staff cutbacks in colleges across the country, due to a reduction in funding from the Department of Education.
It comes after 84 part-time workers were laid off from Dublin Institute of Technology.
USI President Will Priestly said this evening that students will suffer because of a lower number of lecturers and tutors.
He added: "It will also affect the morale of third level teaching staff. Students certainly will suffer because of the job cuts, as the end result will be a lower ratio of lecturers and tutors to students."
