Two years ago, Bijiita Ekka, was a young teenager enjoying school and playing with other children on the sprawling Bundapani Tea Garden in West Bengal, in the foothills of the Himalayas The vast, 3,000-acre (1,214-hectare) property had its own hospital, schools and shops and more than 1,000 families were involved in the growing and processing of tea. Then, in July 2013, the tea garden was shut down. No-one told the workers why - they assume it was not making enough money. In the first 18 months, 10 people died from malnutrition-related illnesses according to Partha Pratim Sarkar, who runs a tea-worker charity, G-Nesep. The government says it is investigating. Others, like Bijiita, suffered a different fate. "We had no money and we had to get money from somewhere," she says. "So my mother took me on a train to Delhi." There they went to see a labour contractor. "There were others there like us," says Bijiita. "One woman suggested that it would be terrible and that we should run away now while we had the chance. But we didn't because we had no money." Bijiita and her mother were locked in an office overnight. Then the pair were separated, and the 14-year-old was taken by train north to Chandigarh, more than 1,000 miles (1,600km) from her home. "I was terrified because I realised that something really bad was about to happen to me and I didn't know what I could do. I had never felt so scared and lonely," she says, her eyes filling with tears. What followed was a life of servitude in a military family that treated her like dirt. "I worked all day and everything I did was wrong. They used to scold me and hit me. Even the children would hit me." She speaks about being constantly hungry, working all the time and being beaten on a daily basis.
