Authenticity is an important concept in positive psychology and has been shown to be related to well-being, health, and leadership effectiveness. The present paper introduces employee authenticity as a predictor of relevant workplace behaviors, namely, employee silence and prohibitive voice. Converging evidence across two studies using cross-sectional and longitudinal designs demonstrates that when responding to hypothetical problematic workplace events (Study 1) or actual workplace experiences (Study 2), individual differences in employees' authenticity predicted more self-reported voice behaviors and less silence that emanated from various motivations. Furthermore, authenticity scores consistently yielded predictive utility over and above the contribution of a broad set of individual and organization-based characteristics. Finally, organizational identification moderated the relation between authenticity and silence, such that for employees with high levels of identification, the relation between authenticity and silence was stronger.Keywords: authenticity, character strengths, employee silence, organizational identification, positive organizational behavior, positive organizational scholarship, voice Authenticity, employee silence, and prohibitive voice 2 Authenticity, employee silence, prohibitive voice, and the moderating effect of organizational identification Authenticity, one of the key concepts in positive psychology research (Seligman & Csikszentmihalyi, 2000, p. 12), "involves owning one's personal experiences, be they thoughts, emotions, needs, wants, preferences, or beliefs" and "expressing oneself in ways that are consistent with inner thoughts and feelings" (Harter, 2002, p.382). Although practitioners and researchers agree that authenticity is important for psychological well-being (e.g., Rogers, 1961;Schlegel & Hicks, 2011), they question the appropriateness of authenticity at work. Studies have revealed that employees are often required to act in specific ways (e.g., Grandey, 2003;Hewlin, 2009;Hochschild, 1983) and that adjusting to others' expectations might be advantageous with regard to supervisor evaluations (Blickle et al., 2011 We think that the potential benefits of authenticity may lie dormant because in some situations, employees who are true to themselves could be beneficial for organizations. One such situation is when employees face problematic situations at work (e.g., transgressions, ineffectiveness). If employees engage in prohibitive voice ...
