Employee voice and silence research shows workers’ ability to express dissatisfaction is impeded by a range of factors. This paper focuses on two: the power asymmetry inherent in the employment relationship, and work context. It examines early career academics (ECAs) – mainly doctoral students, associate lecturers, and assistant professors – many of whom are immersed in atypical, employment or employment-like relationships that are frequently experienced as disempowering. A scoping review provides a frame for understanding ECA voice and silence. It finds there is little on ECAs in the employee voice and silence literature. However, broader concepts of voice and silence are discussed in higher education research on doctoral students and other types of ECAs. Complex work arrangements, difficult supervisory relationships, and hierarchical norms stifle ECA voice. Supervision conceptualised as co-created ‘critical friendship’ facilitates voice. Studies that expand knowledge of ECA voice and silence are recommended, especially as concerns about ECA wellbeing grow.
