The objective of the present study is to identify the dimensions and components of employee prosocial voice and present the relevant model in the municipality of Mashhad. Mixed methods research is used in the current study. The research plan is also an exploratory mixed research project; since the qualitative method was first performed and then, based on the results obtained, a quantitative method was used. The statistical population in the qualitative section was Mashhad Municipality employees who had the experience of prosocial voice for more than twice and had at least 3 years of work experience in the city municipality; 23 subjects were interviewed due to the adequacy of data. Colaizzi’s analysis method was applied to analyze the interviews; as a result, the primary employee prosocial voice model was extracted in three levels. In the first level, four free, promoting, preventive, and ethical aspects were obtained. A questionnaire was distributed among 346 municipality employees of Mashhad in the quantitative section of the study to measure and fit the model. Confirmatory Factor Analysis (CFA) and Amos software were employed for data analysis in the quantitative section. The results of the CFA indicated that all dimensions and components were confirmed. The Comparative Fit Index (CFI) was estimated 0.969 using the Amos software, which indicates fitting of the proposed model. The results of the present study, while helping to develop and implement management improvement programs, could also help improve performance and behavior beyond assigned tasks, such as the employee prosocial voice.
