Citizenship organizational behavior occurs when employees adopt attitudes and perform tasks that exceed the formal functions associated with their roles. Elevated levels of organizational citizenship behavior suggest the presence of positive aspects in the work environment. In this context, this study aims to analyze organizational citizenship behavior in relation to job satisfaction and turnover intention as predictors. Therefore, a survey was conducted using non-probabilistic convenience sampling, with the participation of 102 employees from a public company in the state of Par & aacute;, Brazil. The questionnaire gathered data using the Short Index of Job Satisfaction scale, Turnover Intention Scale, and Organizational Citizenship Behavior Scale. The data were analyzed using structural equation modeling (PLS-SEM), and the results confirmed that job satisfaction has a positive influence on organizational citizenship behavior and a negative influence on turnover intentions. On the other hand, no statistical evidence was found to support the idea that turnover intention influences organizational citizenship behavior. The conclusions recommend the enhancement of human resource management policies to monitor, maintain, or ideally increase job satisfaction. Consequently, these measures would strengthen both organizational citizenship behavior and diminish turnover intentions, ultimately enhancing performance within the studied organization.
