At 6 am everyday, 17-year-old Nisha (not her real name) reports to work for the family that has employed her as its domestic help for the last four years. In the high-rise building in South Colaba in Mumbai where an apartment rents for about a lakh a month, she earns Rs. 2000. She cleans their bathrooms, washes their clothes, and looks after a five-year-old child. She sleeps in a small room attached to her employers' home. But when she needs to go downstairs from the 13th floor where they live, she heads not to the elevator in the front, but to a separate lift at the back of the building.
