The study looked into the general health and well-being of teaching staff at universities, polytechnics, and colleges of education in Delta State, Nigeria, as well as workplace rudeness. It used the ex-post-facto design and the correlational approach. The inability to control the events made the ex post facto necessary. All of the teaching staff at state-owned universities, polytechnics, and colleges of education made up the study's population. One thousand three hundred (1,300) respondents—780 from universities, 260 from polytechnics, and 260 from colleges of education—were selected using the stratified random sampling technique. The "Workplace Incivility Prevalence and General Health of Higher Institutions of Learning Teaching Staff Questionnaire (WPIGHHILTSQ)" is a structured questionnaire used to collect data. After the instrument's face and content were examined, it was put through a reliability test using Cronbach's Alpha, which produced r = 0.86. Descriptive statistics such as mean score and standard deviation were used to analyse the data in order to address research questions while Pearson Product Moment Correlation coefficient was used for hypothesis testing. The study's findings showed that teaching staff at higher education institutions in Delta State, Nigeria, have a high level of workplace incivility, that their general health and well-being are negatively impacted by workplace incivility, and Therefore, it was advised that the administrators of these higher education institutions develop and put into effect workable and practical policies that improve a friendly, healthy, and supportive work environment.
