You Speak, I Speak: The Social‐Cognitive Mechanisms of Voice Contagion
研究通过三个实验发现，员工看到同事提出建设性建议后，会通过增强自我效能感和对建言有效性的信念，自己也更愿意建言，即建言行为具有传染性。
Abstract This study examines whether and how constructive voice (i.e., suggestions intended to promote positive changes at work) is contagious. Guided by social cognitive theory, we propose that witnessing a co‐worker’s voice increases an employee’s propensity to engage in voice via two parallel psychological mechanisms: voice self‐efficacy beliefs and voice instrumentality beliefs. Data collected from a vignette experiment ( N = 661), an experience‐recall experiment ( N = 548), and a field study ( N = 549) provide evidence supporting the proposed voice contagion. The results also suggest that voice contagion is activated by witnessing the voice of any co‐worker, as the evidence supported voice contagion even when controlling for employees’ evaluations of co‐workers’ warmth and competence. Thus, this study contributes to the voice literature by identifying social learning from co‐worker voice as a crucial relational antecedent of employee voice and revealing two possible processes by which voice spreads in the workplace.
