Established voice as a distinct extra-role behaviour — constructive, change-oriented communication intended to improve the situation — separate from helping and from in-role performance. Provides construct and predictive validity evidence distinguishing voice from compliance and from exit. Foundational for the entire organisational voice literature that the PS field draws on: when researchers ask whether PS predicts voice, it is this construct they are measuring. The distinction between voice as discretionary and voice as risky is implicit here and becomes explicit in later work by Detert, Burris, and Edmondson.
