In today’s Québec, the social worker must cope with an unavoidable reality: the cultural diversity among the population. That reality tends to generalize among the social worker preoccupations as much as in their jargon. However, the intercultural social work thought in Québec was confined to ethnic differences between the s.w. and some of her clients. Those differences were imputed to contrasted value systems. In practice, the trend was to build an approach based on the acceptation of other’s values. This might be interesting, but it is certainly insufficient to define the nature of intercultural practice. This article proposes to address the limitative and sometimes wrong aspects of the current intercultural social work thought and to define the principles of a model based on a semiotic and narrative approach of signification systems.
