My goal, therefore, is to review and integrate the existing theory and
research and also to provide some direction for future scholarship by highlighting
important questions that still need to be answered. I begin by reviewing the
different conceptualizations of employee voice. My intent is to define clearly
the voice construct and clarify how it relates to, yet is conceptually distinct
from, other constructs that share commonalities with voice. I then provide a
comprehensive review of the existing theoretical and empirical research on
motives, antecedents, and outcomes related to employee voice. Following
this, I focus on what I see as the important unanswered questions in the literature
with the hope that this will generate and provide direction to future theory
building and research.
