Background: A family nurse, next to a family doctor and midwife, plays a crucial role in the primary health care system, and a patient has the right to choose them; they are the first medical professional the patient meets when there is any problem. The present study aimed to define the level of job satisfaction among Polish family nurses and to establish its standards. Attempts were made to assess whether job satisfaction depends on the job location, form of employment, family structure, or financial situation. Method: A cross-sectional study was conducted among Polish family nurses who were professionally active in 2018. As the first step, the questionnaires were sent to all (45) County Chambers of Nurses and Midwives in Poland. The data were collected and analyzed using a standardized questionnaire “The Satisfaction With Job Scale” by A.M. Zalewska and our survey questionnaire. Results: Of 220 family nurses surveyed, 219 (99.5%) were females and one (0.5%) was male. The mean age of the study participants was 50.13 years, with a standard deviation of 8.36. The majority of nurses had secondary education (37.6%), with a qualification course (96.2%), without specialization (61%), with a nursing job seniority of 30–39 years (44.6%), and residing in a medium-sized city (43.7%). In the study group, the mean score of job satisfaction was 22.23 (on a scale of 35), and median (Me) score was 23. Conclusion: The results of the study revealed that Polish family nurses are moderately satisfied with their job. A higher level of job satisfaction was reported among family nurses with longer job seniority, who are working in the country, are owners or co-owners of a primary health care unit, live in a complete family, are single, and who declared that they could afford what they wanted to buy and possessed savings. Moreover, the level of job satisfaction was highest among the nurses who recommended other nurses to work in a primary health care unit, participated in scientific conferences, and subscribed to nursing care journals.
