Research supports bullying as a precursor of school violence and establishes this form of campus aggression as a public health issue. The literature that complements safe campus environments also aligns with school climate, suggesting that organizational citizenship behavior (OCB) mitigates student bullying. Employing data from 108 public elementary schools in Texas, we explore whether OCB predicts 2 facets of bullying: student bullying and teacher protection. The investigation also examines the relationships among OCB, socioeconomic status (SES), school size, and bullying. The hypothesis that OCB is negatively related to student bullying and positively related to teacher protection is supported. Moreover, correlational analysis reveals significant relationships among the variables, and regression analyses identify OCB and SES as statistically significant predictors of teacher protection of students in schools. Finally, when combined with school size, OCB and SES accounted for a significant portion of the variance in teacher protection and student bullying.
