THOUSANDS of workers from across Tamil Nadu took part in a rally in Chennai on April 4, demanding a curb on price rise, check on rising unemployment, abolition of the contract system and equal pay for equal work, an end to violence against women at work place, and a minimum wage of Rs 18,000, among others. The 13TH Tamil Nadu state conference of the CITU had given a clarion call to the working class to lay siege to the Fort St George, the state secretariat, over these long-pending demands of the people, particularly the workers.
