In fact they knew nothing about the Nike company at all. The reality they live each day is one of threats, humiliations, intimidation. They are told they cannot speak or even wear makeup. They need permission to use the bathroom or to drink water, and they are told when they can or cannot go. If they tried to learn their rights and defend themselves they would be fired.
Every worker knows that.
It is a trap they cannot get out of. Before representatives from North America arrive, the factory is cleaned and for a few hours during the visit, the workers are treated decently. It is a staged event. When the visitors leave, everything returns to the normal abuses. No attempt is ever made to speak with the workers in a safe location where they are with local respected religious and human rights organizations they can trust and confide in.
