CNN — Mercy Esther was eight years old when she left home. Raised by her grandmother in rural Tanzania, Mercy Esther and her siblings were born into poverty, sometimes without money for food, let alone schoolbooks. When their grandmother was approached with a job offer for Mercy Esther in Kenya, and the promise that money would be sent home, she accepted. The money could help Mercy Esther’s siblings. They might have a better future. The job offer turned out to be a lie – the first of a string of broken promises that would deprive a young woman of her childhood and her family. Mercy Esther was born with a deformity in one foot, causing a pronounced limp. On the streets of Nairobi she and other children were forced to beg. She was told to pretend she could not walk, to elicit sympathy from the public. Each day, what money she collected was taken from her. One day, while begging, Mercy Esther was approached by a woman who offered her domestic work and more promises: a new home, a wage and good treatment. She went with the woman, but instead Mercy Esther was abused and received no money for her labor. It would be six years before she ran away. More from the CNN Freedom Project With the support of the Nairobi police and Kenyan and Tanzanian governments, Mercy Esther returned to the country of her birth, but without details of the village where she was raised, authorities put her in the care of WoteSawa Domestic Workers Organization, which runs a shelter for trafficked children in Mwanza, on the shores of Lake Victoria, in the north of the country. Mercy Esther spent years in domestic servitude without pay. Marek Klosowicz/Kulczyk Foundation “All are equal” “Tanzania is a beautiful and a peaceful country, but there is a dark side,” said Angela Benedicto, the organization’s founder and executive director. “Many people live in poverty, and forced labor is a very big problem,” she added. “The most common form of human trafficking in Tanzania is domestic servitude, young girls forced into domestic work. They face abuse, exploitation, and are not paid for their work.” Around one million children – mostly girls – are engaged in domestic work in Tanzania, according to the non-profit Anti-Slavery International. WoteSawa was set up in 2014 and every year takes in around 75 children who have escaped trafficking. Space is tight: children sleep two to a bed. Some stay longer than others, says Benedicto, particularly those involved in criminal cases, as prosecutions can take time. So far, the non-profit has helped hundreds of survivors, but the needs are greater than the resources available. Benedicto dreams of building a bigger haven for more children. Her mission is to empower domestic workers and advocate for their rights. It’s an issue that’s close to her heart; she is herself a former domestic worker. “I faced abuse and exploitation, but I was able to speak out,” she explains. “Many domestic workers, they can’t speak out. Who is going to speak (for) them?” “I’m using my story to tell them, ‘Don’t give up.’” WoteSawa means “all are equal” in Swahili. At the shelter children are housed and provided with counseling and legal support. They also receive an education in literacy and numeracy, and vocational skills such as needlework. Reintegrating children back into education works in step with efforts to reunite children with their loved ones, “so that when they go back to their families, they can help not only themselves, but they can help their families,” said Benedicto. Fighting trafficking through education Lydia lives in the Ngara district in the mountains of Western Tanzania. She left home to become a domestic worker aged 16, but was beaten by her employer and not paid for her work. She escaped and was helped by WoteSawa, where she learned how to sew. Lydia returned to her family with a sewing machine provided by WoteSawa and today she is a dressmaker with dreams of a shop of her own. Sugam Pokharel/CNN Related article Silk slaves: India’s
