Ramaswami: Patna: Thousands of striking contractual school teachers in Bihar are disappointed with no response from President and Prime Minister even after 10 days have passed since they requested for an intervention in view of the increased hardships under the lockdown. Now, they have approached the National Human Rights Commission seeking a probe into the death of 62 teachers during the strike period. "We are really upset as there is no reply from the office of the President of India Ramnath Kovind and Prime Minister Narendra Modi.We had written to both requesting to intervene to help over 4 lakh striking teachers and their families. But so far we have not received any response. This shows how helpless are school teachers," Manoj Kumar, a leader of Bihar Rajya Shikshak Sangharsh Samanvay Samiti said on Tuesday.
