Speaking up behavior plays an essential role in improving the service quality of teams and organizations. This study uses cross-level polynomial regression to explore the influence of supervisor–frontline employee power distance orientation (PDO) congruence on the speaking up behavior of frontline employees. The results indicate that congruence (vs. incongruence) in supervisor–frontline employee PDO can lead to more speaking up behavior. In addition, we propose an asymmetrical incongruence effect such that speaking up behavior will be most when supervisors are low in PDO and frontline employee are high in PDO. A team-oriented incentive structure also moderates the relationship between supervisor–frontline employee power distance orientation and speaking up behavior. These findings not only help us better understand the antecedents of frontline employee speaking up behavior, but also provide important implications for hospitality management.

说出行为对于提高团队和组织的服务质量至关重要。这项研究使用跨级多项式回归来探讨主管一线员工的权力距离定向（PDO）一致性对一线员工的口语行为的影响。结果表明，主管一线员工PDO的一致性（相对于不一致）可以导致更多的口头表达行为。此外，我们提出了一种非对称的不一致效应，使得当主管的PDO偏低而一线员工的PDO偏高时，说出来的行为最多。以团队为导向的激励结构还缓和了主管一线员工的权力距离导向和大声讲话之间的关系。
