Unethical communication occurs fairly frequently in organizations, yet confronting someone about an ethical transgression is a politically sensitive interaction that challenges people’s identities. This study integrates a social confrontation approach and politeness theory to identify politeness strategies people perceive as effective and socially appropriate for expressing disapproval of ethical transgressions. To examine the extent to which the selection of politeness strategy was related to the type of unethical communication and power in the relationship, participants evaluated hypothetical scenarios based on Redding’s proto-typology of unethical communication. The type of unethical communication influenced perceptions of the appropriateness and effectiveness of three politeness strategies and the power relationship influenced perceptions of two politeness strategies.
