In 1971, she decided to leave her job and return to Calcutta. She started her political work as a student activist since under the guidance of the Party she enrolled as a student in Calcutta University. On the suggestion of the party to understand practical politics, she joined the Calcutta University. Initially she worked with students in the college campus and later during the Bangladesh war at refugee camps in the State. She was also writing for the Party weekly and later became a full-time worker there. In 1975, she shifted to Delhi "In 1975 I shifted to Delhi because I wanted to work in the trade unions. At that time our party general secretary was Comrade P. Sundaraiah. He was ahead of his time. He had a clear perspective of the area of work to assign workers. He had a sensitive cadre policy. I was privileged to join the party in Delhi when he was the leader. I was accepted and got my membership."
