Students of electro-medical engineering course of Barisal Polytechnic Institute on Monday morning formed a human chain demanding government jobs and higher education facilities. The human chain was formed in front of Aswani Kumar Hall in the city. The students said diploma course on electro-medical engineering is running in nine government polytechnic institutes of the country. The course was introduced with an aim to provide skilled manpower for maintenance and servicing of electro-medical instruments in the health service providing organisations. But the general electricians are getting job in public hospitals or health service providing institutions while the skilled students passed from the electro-medical engineering department are sitting idle for lack of higher education facilities, they alleged.
