ABSTRACT Objective: To identify work aspects that generate satisfaction for the professionals who work in the Family Health Strategy. Method: This was a qualitative, descriptive study that involved five geographical regions of Brazil, and 27 Family Health Teams from six municipalities. The data were collected from 76 health professionals using semi-structured interviews, and were analyzed articulating the three phases of content analysis using Atlas.ti software resources. Results: The findings showed 129 statement excerpts, with 14 codes, grouped into three categories related to satisfaction. The category, Job Identification and Family Health Strategy Principles, represented 40.3%, with the codes: team work, job affinity, health model, completeness of care, and longitudinality of care. The category, Relationship with Family Health Strategy patients, represented 32.6%, with the following codes: bonding with patient, resoluteness of care, patient satisfaction, and patient care. Finally, the category, Professional and Working Aspects related to the Family Health Strategy, represented 27.1%, with the following codes: relationship with professionals, work recognition, enjoying the profession, team organization, and employment relationship. Conclusion: Professional satisfaction is associated with the work principles of the Family Health Strategy, and with the relationships that are established between patients, professionals and health management. It also has a subjective dimension, with a strong relationship with characteristics of the work process, how it is organized, and under what conditions and relationships this work occurs.
