It analyzes the factors related to the identification, notification, and recognition of child labor as child and youth violence by professionals from the Family Health Strategy in Manaus, Amazonas. The research used a cross-sectional study method and covered 611 professionals (52.5% of those eligible) from basic health units. Data were collected through self-completion of a questionnaire, consisting of the following modules: sociodemographic characteristics; professional training and performance; and level of knowledge regarding aspects of child and youth violence. For bivariate analysis, Pearson's chi-square, and Fisher's exact tests (p<0.05) were used. The results indicate that only 4.8% of professionals identified situations of child labor during their work in the Family Health Strategy and only 13.1% recognized the domestic modality. Participation in training on child and youth violence (p=0.018) and self-report of violence in childhood (p=0.024) were statistically relevant for identifying child labor. Regarding the recognition of domestic child labor, the highlights are the level of education (p=0.013), the length of training (p=0.049), participation in training on child and adolescent violence (p=0.004) and the level of knowledge (p =0.003). The professional category (p<0.001) was relevant regarding the intention to notify. It is concluded that reducing child labor requires visibility of the problem and an understanding of the severity of the repercussions for the individual's development. The research demonstrated the importance of continuing education, through participation in training on violence against children and adolescents with a focus on identification, notification, and awareness strategies for health professionals.
