He was the founder architect leader of Assam State Power Workers Union and worked to build up continuous resistance movement against privatisation of Assam State Electricity Board. Despite his illnesses, till his death, he continued to carry forward the work of the union. It was under the leadership of Comrade Rajkonwar that a 72-hour historic strike was organised in the power sector of Assam. Comrade Rajkonwar worked hard to ensure the integration of the power workers in the mainstream working-class movement of India.
Comrade Ajoy started his party life as cultural activist of Sadou Asom Janasanskritik Parishad and joined the party in 1982. He enjoyed wide respect amongst party cadre and members as an honest, responsible dynamic and an affectionate comrade. He was elected to the state committee of party. Comrade Ajoy always maintained close relation with various social organisations apart from our class and sectional organisations. With the death of Comrade Ajoy, the party lost a long-standing activist and the working class movement has lost a popular, dynamic and a uncompromising leader of workers. Red salute to Comrade Ajoy Rajknowar!
