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.

你说，我说：声音传染的社会认知机制

本研究考察了建设性的声音（即旨在促进工作中积极变化的建议）是否以及如何具有传染性。在社会认知理论的指导下，我们提出目睹同事的声音会通过两种平行的心理机制增加员工参与声音的倾向：声音自我效能信念和声音工具信念。从小插图实验 ( N  = 661)、经验回忆实验 ( N  = 548) 和实地研究 ( N = 549) 提供支持提议的声音传染的证据。结果还表明，声音传染是通过目睹任何同事的声音来激活的，因为即使在控制员工对同事热情和能力的评估时，证据也支持声音传染。因此，本研究通过将来自同事声音的社会学习识别为员工声音的重要关系前因并揭示声音在工作场所传播的两种可能过程，为声音文献做出了贡献。
