TIP stands for Trafficking in Persons. As mentioned in my post on rescue work, us ordinary laypeople should never try to rescue trafficked victims by ourselves. Instead, we need to call the proper authorities* and let them handle it. That said, many anti-trafficking organizations offer TIP training, which prepares you to know a trafficking situation when you see one. If you would like to attend a TIP training in your area, please visit the links page and contact anti-trafficking organizations in your state to find out where and when the next one is being held. Please note that not all organizations will refer to it as TIP.
*If you see something that appears to be a trafficking situation, please call 1.888.3737.888 and report it.
