Employee voice is a much studied but poorly integrated topic. There is great interest in understanding why and how employees voice, or remain silent, in the management disciplines of organisational behaviour, employment relations and human resource management, but these fields have diverging conceptualisations of the voice phenomenon. This chapter argues that there is much to gain from a research agenda seeking to integrate voice perspectives and conceptualisations, and signals how researchers might be able to break away from existing silos that hamper our understanding of a phenomenon that all researchers agree is critical for organisational success and employee well-being.
