There are 25 lakh registered construction workers in Karnataka, with about 25 per cent employed in Bengaluru, according to Errol Fernandes, the vice-president of the Confederation of Real Estate Developers’ Association of India (CREDAI), Bengaluru. After the disruptions caused by Covid-19 lockdowns, the slow vaccination process is adding to the worries of real estate developers, who fear that a prolonged staff shortage may hit project timelines. For health safety reasons, many builders are calling to sites only those workers who have taken at least one dose of the vaccine. The number of such workers is not big currently.
