Nearly 100 construction workers took out a rally from Kamla Nehru Park near Sadar Bazar till PWD minister Rao Narbir Singh’s residence on Friday morning to protest against mandatory online registration of workers. According to the protesters, many workers do not have means or knowledge for online registration and the state government should give them an option of offline registration, as well. “All workers’ benefits are linked to their registration cards. However, of late, workers are having trouble getting themselves registered or renewing their registrations as the process is online,” said Rajinder Singh, district secretary, Centre of Indian Trade Unions (CITU), Gurgaon.
