TEN years after the Bhopal tragedy, a former Union Carbide India Ltd (UCIL) plant operator in his book, Bhopal: The Inside Story, says that the UCIL contention that a disgruntled worker was responsible for the accident is bunkum. With supportive testimonies from 15 workers, including the one being blamed by UCIL, the book says that despite knowing about MIC's toxicity, the Carbide management had not followed stringent plant designs and operational rules, leading to the accident.
