With the Vijaya case, Prabha realised that the Irulas were subjected to harassment by their employers as well as civic and police authorities. And unlike the Dalits who were a political and numerical force, the Irulas were on the margins. The tribe, traditionally rat- and snake-catchers, have often been featured in exotic foreign documentaries. But today, they are predominantly employed in rice mills and brick kilns in Cuddalore and Villupuram districts. Only 12 per cent of them are literate. "They are almost like bonded labourers. The work itself is dangerous and physical abuse at the workplace is rampant," says Prabha.
