Unethical employee behavior (UEB), an important organizational phenomenon, is dynamic and multi-faceted. Recent renewed interest in the role of emotion in ethical decision-making (EDM) suggests that unethical behaviors are neither always rationally derived nor deliberately undertaken. This study explores how to integrate the conscious and nonconscious dimensions of unethical decision-making. By broadening the scope of inquiry, we explore how integral affect—the emotion tied to anticipated decision outcomes for the employee engaging in misconduct—can shed light on UEB. We review related literature on affect and EDM and propose a model in which we assert that at a decision point, an employee experiences multiple integral affects that are either persuasive or dissuasive toward UEB. We further posit that among these integral affects, a dominant integral affect (DIA) emerges, determining the nature and direction of unethical behavior. In addition, our model considers the role of affective residue and the influence of other factors, such as incidental affect, disposition, context, and retrospection, to derive propositions. Our DIA model can help managers gain a comprehensive understanding of how affect, characterized by its locus (self or other orientation) and valence (enhancing or harming), determines the characteristics of UEB.
