This study aims to analyse social logics that condition the reconversion of the activity of syndical auxiliaries in fund extorsion. To do this, a survey was carried out with syndical auxiliaries in the district of Abidjan especially in Abobo. Qualitative approach through open interviews, allowed us to collect necessary data to achieve the following results: liberalization of urban collective transport carried away proliferation of syndical structures formed of actors with divergent objectives in sight of obtaining incomes of this sector. Profit-seeking led some syndicates to redeploy themselves in fund extorsion actors to the detriment of defending interests of drivers.
