Objective: The objective of the study was to determine the job satisfaction of public workers in the provincial municipalities of the Tumbes region (Peru). Method: The method used was a descriptive, non-experimental cross-sectional design. The sample consisted of 319 male and female workers from the 3 provincial municipalities. A sociodemographic questionnaire and the Job Satisfaction Questionnaire were used as data collection instruments. Results: The results showed that only 10% of the participants had high job satisfaction. Within the dimensions, the majority showed low satisfaction (67%) with the remuneration received. No significant differences were found between men and women with respect to job satisfaction, and those with permanent employment status had lower levels than those who work on a temporary basis. Conclusions: It is concluded that most of the personnel working in the provincial municipalities of the Tumbes region have low levels of job satisfaction, so it is important to develop programs aimed at strengthening the bond and favorable attitude of workers with the institution where they work.
