This article explores employee voice within organizations, in the context of the often-complex inclusion of sexual and gender minority (lesbian, gay, bisexual, trans and intersex (LGBTI)) employees. This study utilized a qualitative case study approach to gather insights from diversity experts and organizational documents of three large Australian organizations representing private, not-for-profit and public sectors. This research focused on organizational interventions that capture the voices of LGBTI employees, because their voice remains a challenge. While extant literature has largely focused on employee networks as a primary voice for this group, this study identifies several other integral and novel mechanisms. This study contributes to existing knowledge by developing an empirically based theory on voice mechanisms to overcome the spirals of silence. The findings of this study offer practical value to organizations seeking to promote LGBTI voice and inclusion in the workplace. JEL Classification: J15, J16, J71, J81, M12, M14, O15
