You need to find an entry point, a way of approaching workers. The most common entry point is through a contact person. Where possible, get someone to introduce you to a potential contact person from the target group. This can help to open doors, and overcome distrust, fear and reluctance. The person should be someone workers trust, respect and have confidence in. It may be the official or unofficial leader of a group or association of workers, or a leader in the community. On the other hand, the leaders of a group or association may be the very people that workers fear or distrust. Here you may have a problem. If you bypass the leader, he may turn hostile and undermine organising efforts. If you work with the leader, the workers may reject your organising attempts. There is no easy answer to this problem. Be aware of it and be prepared to change your strategy.
