The purpose of this quantitative study is to explore the frequency of uncivil behaviors amongst teachers. The research seeks to determine leadership support and job satisfaction levels in order to relate their relationship to turnover. Fulfillment of teachers' basic psychological needs is essential for optimal performance and growth. The 2018 Indiana Department of Education Teacher survey data shows low favorability levels regarding school leadership trends and collegiality in schools. The researcher examined the perceptions of the educators in a region of Indiana. This research study was compared with a similar study completed in an urban school district in Western Central Illinois. The researcher used an electronic survey, via Qualtrics, to gather demographic information and determine the extent of teacher-to-teacher uncivil behaviors as well as levels of leadership support and job satisfaction. A total of 74 teachers participated in the research study. Overall, 10.9% percent of respondents perceived themselves to be victims of uncivil behaviors on a weekly or daily (regular) basis. Strong statistical significance was found between uncivil behaviors and job satisfaction, leadership support, and teacher turnover. A recommendation from this study is that teacher turnover can be reduced when leaders meet the intrinsic needs of their teachers.
