This is a qualitative study, based on comprehensive sociology, which aimed to understand the meaning assigned by health professionals of Belo Horizonte-MG, Brazil, to the principle of resolvability in the everyday actions of health. Thirty-two workers were the informants of this research. We used a semi-structured interview technique and content analysis. Professionals describe what is the solution and the factors that hinder their achievement. They realize, too, that patients do not always leave the Units with the response they want; and that the service is resolute in that matches your level of attention, although for some people and managers is the reverse. We conclude that it becomes urgent to reorganize aspects of this doctrinal principle of SUS.
