`titrebInventing the 21st century’s social work: an ongoing and collective development of practices`/titrebWhat strikes most when reading former French minister of social Affairs Nicole Questiaux’s “Main guidelines on social work” is that, thirty years after it was published, it is almost topical again.Within the unprecedented disruption our society has undergone since the 80s, notions of citizenship, democracy, community, territory and decentralization highlighted in this work echo in a different way today, but with the same force.These ideas echo with the question of social work “users”, for whom “doing with” rather than “doing for” is an issue that must be constantly supported and evaluated. They echo with decentralization and public policies territorialism, even though on this subject corporate governance must guarantee, again and again, the transversality that is essential to such complex situations.Expectations towards social work players, policy makers, supervisors or social workers are great and today’s major issue is what social work will serve as in the social agreement and the ambition to build a society. We must invent social work for this 21st century and the invitation is open to policy makers, stakeholders, social workers and citizens themselves.
