Dubey was closely connected with the trade union movement in the coal, steel, engineering, power and sugar industries. He was also closely associated with Indian National Trade Union Congress and became its national president in 1984, having previously been a state president until his last breath. He was also the president of many other labour unions, such as the Rastirya Colliery Mazdoor Sangh (RCMS), the
Indian National Mineworkers' Federation (INMF), and the Bokaro Steel Workers Union. Dubey started his Trade Union movement in the mid-1940s before independence when the collieries of India were in private hands where colliery owners and contractors used to exploit the contract labourers. He campaigned for better wages and working conditions for coal miners, visiting many countries like West Germany, the United Kingdom, Belgium, the Netherlands, France, Yugoslavia, Switzerland and Japan to acquaint himself with employment conditions in mines and factories. He represented the country at many international labour conferences and seminars. == Legacy ==
