讲座简介：

In today’s highly uncertain business environment, employees proactively pointing out potential hazards—known as prohibitive voice—serves as the organization’s first line of defense against workplace risks. However, speaking up often entails significant personal and interpersonal costs. Who truly dares to break the silence?

Traditional organizational behavior literature generally assumes a linear relationship, suggesting that only employees with an internal locus of control (LOC)—those who believe they control their own destiny—are willing to voice concerns. This talk will share a recent study published in the Journal of Applied Psychology that challenges this long-standing consensus by revealing a counter-intuitive U-shaped relationship between LOC and prohibitive voice.

Drawing upon the demands-abilities fit framework, this research demonstrates that employees with either strongly internal or strongly external LOC actually perceive lower risks associated with speaking up compared to those with moderate LOC, resulting in greater engagement in prohibitive voice. Furthermore, this mediated U-shaped relationship is most pronounced when the team voice climate is low—meaning these unique traits shine brightest exactly when speaking up feels the riskiest.

Findings from two field studies with a multisource, multi-wave design support the proposed moderated mediation model. Overall, this research refines our understanding of why and when employees speak up about problems at work and suggests ways managers can better foster such behavior in situations that feel risky.
