Guided by a framework for multilevel construct validation, this study identified incivility climate as a new facet-specific climate construct. Referring to shared perceptions about the uncivil behaviors, practices, and norms that exist within a team, the construct of incivility climate is fundamental for future research investigating and estimating the effect of workplace incivility at the team level. Data from three separate samples totaling 1,110 employees and 50 work teams were used to test the internal consistency, confirm factor structure, and assess convergent and incremental validity of a new measure at both the individual and team level. The results support the construct validity of incivility climate along with the utility of the Team Incivility Climate Scale. Theoretical implications and practical applications of the construct and measure are described.
