The employees, who work in the country's public colleges as office assistants, computer operators and security guards on a temporary basis, have demanded nationalisation of their jobs.
They have also demanded that they be paid salaries as per the government pay-scale until their jobs are regularised.
They placed the demands at a sit-in programme in front of the National Press Club on Thursday.
Around 200 temporary employees from different public colleges across the country participated in the programme organised under the banner of "Sorkari Colleger Besorkari Kormochari Union" (Union of the temporary staff working in public colleges).
Dulal Sarder, president of the union, said, "We work as much as the government employees do. But our monthly salary is Tk6,000-Tk7,000. Is it possible to run a family with the salaries we get? So finding no other way, we have held the sit-in programme. We will continue the programme until our demands are met."
Another leader of the union said there were around 8,000 employees, who were working in 340 public colleges across the country on a temporary basis. All of them were going through the same condition, he added.
They have already submitted a memorandum to the Directorate of Secondary and Higher Education, the secretariat and the Prime Minister's Office in this regard.
Mojibor Rahman, general secretary of the union, said, "We are deprived. Now, we have taken to the street as we do not have any other way."
