You're correct to say it's economic migration or migrating because you're coming from a desperately poor village and moving to a neighbouring country. For example, you're a Cambodian going to Thailand or an Ethiopian going to the Middle East. That is often why people end up in exploitative situations like slavery or bonded labour. The recruitment process is really key to ensuring that this doesn't happen.
Our work varies in each country. In central Nepal, it is about removing prepubescent girls from the sex industry; in Tamil Nadu, it's about aiding girls and preventing them from being exploited and going into bonded labour.
Liberation looks different in every place. Sustainable liberation is about ensuring that people go through appropriate trauma recovery, and then have sustainable vocations that they can move into so that they're not re-trafficked or vulnerable to re-trafficking.
