Bikas Sardar, 34, has been working as a migrant labourer for more than 10 years. He is semi-literate and unskilled, and, therefore, Sardar never had the luxury of holding a permanent job at one particular location. Sardar went where the labour contractor took him. In the last four years, he has been working at construction and pipeline-laying sites in Bengaluru, Chennai, and Kolkata.
