Building on agency theory and signaling theory, this study investigated the psychological mechanism of how empowerment impacts hotel frontline employees' self-esteem, perceived trust, and OCBs performed toward both internal and external customers. Using a longitudinal research design with data collected via three waves, the results supported that three out of four dimensions of empowerment had significant and positive influence on employees' self-esteem and perceived trust, both of which are significant predictors for three types of OCBs. The study makes important contributions to literature and suggests that hotel employees feeling empowered can enhance their overall wellness while contributing to their OCB performances. Thus, empowerment should be properly used as a strategy to facilitate employees’ contextual performance.

基于代理理论和信号理论，本研究调查了授权如何影响酒店一线员工的自尊，感知的信任以及对内部和外部客户执行的OCB的心理机制。使用纵向研究设计以及通过三波收集的数据，结果支持授权的四个维度中的三个对员工的自尊和感知到的信任有显着且积极的影响，这两者都是三种类型的OCB的重要预测指标。这项研究为文献做出了重要贡献，并建议感到被赋予权力的酒店员工可以提高整体健康水平，同时为他们的OCB绩效做出贡献。因此，应适当地将授权作为促进员工情境表现的策略。
