Over 1,000 students have protested at Waterford IT over a row between lecturers and college authorities, which has left an estimated 10,000 students without their exam results.
The dispute concerns payments to be made to Institute lecturers for correcting exams at the end of each semester.
The Teacher's Union of Ireland says rates of pay for correction of examinations at Waterford Institute of Technology were changed unilaterally and without consultation with staff.
WIT insists that the move brings the rate of payment in line with norms in the Institute of Technology sector.
Lecturers have since refused to give the students at the college the results of exams that were taken before Christmas.
Students say it is not fair being dragged into an industrial dispute that does not involve them.
Talks are taking place between the union and management and it is hoped that a resolution can be reached.
Waterford Institute of Technology has requested the Labour Relations Commission to help resolve the current impasse.
