It is an unfortunate situation that staff are disrupting students, however, we do not know what is going to happen," University of Mpumalanga Dean of Students Dr Paul Maminza said.Maminza said the university had handed a list of demands from staff members, who belong to the National Education, Health and Allied Workers' Union (Nehawu), to the Department of Higher Education (DHET) last week."A memorandum was handed to the DHET last week Thursday. We are still waiting from direction regarding the staff members demands," Maminza said.Cars damaged No students were injured during the demonstration, but three vehicles were damaged.The university was still hopeful, despite the disruptions, that examinations will continue."We have not sent students home. They are still on campus and we are hopeful that these protesters will allow students to write their examinations," Maminza said.Police said they would maintain a presence until peace was restored."We are there to engage with relevant parties to ensure that learners write their exams and we will continue with maximum police presence at the University," Hlathi said.
