Tea pickers live in housing known as "lines", a number of linearly attached houses with just one or two rooms. This housing system and the environmental sanitation conditions are generally poor for labourers in the plantation sector. There are typically 6 to 12 or 24 line rooms in one line barrack. The rooms lodge as many as six to eleven family members, and are often without windows. In the housing system for plantation workers in Sri Lanka, women and girls have no privacy from the male workers, which places them at a high risk for sexual harassment. In June 2007, a study conducted in the Nuwara Eliya tea growing area revealed that the serious lack of privacy has led several women to commit suicide, especially newly wedded women. According to studies by Christian Aid, the female Indian Tamil plantation workers are particularly at risk from discrimination and victimization. Some concern towards women's rights have been made in regards to the female plantation workers in Sri Lanka, resulting in some 85 neighbourhood women's groups being formed across the country, educating them in gender, leadership and preventing violence against women.
