Express News Service CHENNAI: Small and micro industries in Guindy and Ambattur are struggling to survive by keeping their units open during the second wave of the COVID-19 pandemic to meet stringent deadlines and ensure they deliver their orders on time. With many of the employees testing positive and the workforce declining, deadlines are not being met and they risk being blacklisted by larger companies who have given them orders. "Small industries are a vulnerable lot and with the rise in cases in the second wave of the pandemic and migrant workers fleeing, it is difficult to meet deadlines," says T V Hariharan, president of Chennai District Small Scale Industries Association.
