Schools across the globe and especially in Nigeria have witnessed situations in which teachers work outside their work ethics. This situation breeds exhibition of work deviant behaviors among the teachers at different levels of education as evidenced in the literature. However, literature is scarce on the influence of teachers' demographic characteristics on their work deviant behaviors in primary schools. Thus, this study was necessitated to explore the determinants of work deviant behaviors of rural community‐based primary school teachers in Enugu State, Nigeria. This study was anchored on the affective events theory propounded by Weiss and Cropanzano. Basing the study on the quantitative research approach, a correlational survey research design was adopted using a sample of 254 rural community‐based primary school teachers. Necessary information for the study were collected using researchers' adapted questionnaire on work deviant behaviors with 28 items. The questionnaire items had an internal consistency reliability index of 0.87. Data collected were analyzed using hierarchical multiple regression analysis and the structural equation modeling approach. It was revealed that among the demographic characteristics (age, working status, qualification, marital status, gender, years of teaching experience, and location) of the teachers, only age and qualification were found to be significantly (p < 0.05) related to work deviant behaviors. The implication of this study, therefore, is that the age and qualification of rural community‐based primary school teachers determine the nature of their work deviant behaviors. Thus, it was recommended that the age and qualification of teachers should be considered very paramount in the employment of teachers.
