This research examines how people perceive and respond to potential conflict in work settings. When individuals highly value their interpersonal relationships with others, they may take the potential costs to relationships into consideration in deciding how to handle conflict. We propose that individuals take an avoidance approach to conflict to prevent disruption in relationships from confrontation. Specifically, the value that individuals place on superficial harmony is positively related to their negative anticipation of relationship costs, which in turn leads to conflict avoidance. Furthermore, the direct relationship between superficial harmony and negative anticipation and the indirect relationship between superficial harmony and conflict avoidance are negatively moderated by the closeness of relations between the parties involved. The results of two studies conducted in workplace settings supported our hypothesized moderated mediation model. Highlighting the role of superficial harmony in conflict avoidance, this research contributes to the existing literature on conflict management and has practical implications for effectively managing conflict in the workplace.
