The study of the personnel of regional councils (based on both a national sample and on one case, that of Brittany) can be envisagea only in a plural framework. Statutory heterogeneity increases the specificity of personnel policy in each of the regions. A strong trend has appeared : national higher civil servants have moved to the regional services in order to gain a guaranteed supremacy in jobs of high responsibility at the top of the hierarchy. Can and will the council's executives contribute to the definition of a genuinely regional administration ? The rocky and diverse landscape of regional administration suggests that a simple statute for territorial public service is difficult to conceive.
