A decade-later sequel to Morrison's own foundational 2014 review, tracking how the voice and silence literature has grown roughly tenfold in publication volume since then. A systematic search (PsychInfo, PsychNet, ABI-INFORM, 2014–2021, restricted to top-tier journals) yielded 158 papers. Defines voice narrowly and deliberately: informal, discretionary, upward communication intended to bring about improvement or change, excluding peer-only voice and external whistleblowing, and explicitly pushes back against Maynes and Podsakoff's (2014) broader framework (which folds in 'destructive voice' and 'defensive voice') as abandoning the construct's defining prosocial, change-oriented character rather than sharpening it. A second, harsher critique is reported at length rather than dismissed: industrial and employment relations scholars accuse the organisational behaviour voice literature of being a narrow, individualistic, managerialistic silo that only recognises voice serving management's interests and almost entirely ignores collective and formal mechanisms like unions and works councils, a critique Morrison partly concedes even while defending the OB definition itself, and returns to as a genuine gap the field needs to address. Charts a real methodological shift: increasing use of Liang, Farh and Farh's (2012) promotive (suggestion-focused) versus prohibitive (problem-focused) voice distinction over the older undifferentiated Van Dyne and LePine (1998) scale, since the two forms turn out to have meaningfully different predictors, outcomes, and even different emotional costs to the person voicing (prohibitive voice increases the voicer's own anxiety; promotive voice increases pride). The paper's single most consequential finding is Sherf, Parke and Isaakyan's (2021) direct challenge to the field's usual assumption that silence is simply the absence of voice: their meta-analysis and six-month panel study show voice and silence are driven by genuinely independent regulatory systems (voice by behavioural activation, responding most to perceived impact; silence by behavioural inhibition, responding most to psychological safety), meaning research can't simply flip the sign on voice predictors to explain silence, as much of the literature had implicitly assumed. Along the way, the review surfaces a long list of nuances that complicate tidy advice: an inverted-U relationship between leader-member exchange and voice (too much closeness can suppress it, not just too little); a U-shaped relationship between job satisfaction and voice; supervisors giving more credit for voice to higher-status employees even when lower-status employees speak up more often, meaning speaking up more doesn't compensate for whose voice gets recognised; and, in a genuinely counterintuitive finding on formal mechanisms, employees with more access to formal voice channels like suggestion boxes reported using them for helpful ideas while becoming more selective about withholding anything that might disturb group harmony, undercutting the assumption that simply adding a channel increases candour rather than just redirecting it. A 33-country study of silence motives found power distance predicts more acquiescent and prosocial silence but has no relationship with fear-based silence specifically, complicating the standard assumption that high-power-distance cultures simply produce more frightened employees across the board. Morrison is candid about the field's fragmentation throughout, noting at one point that the sheer length and inconsistency of the mediator and moderator list for leadership and voice makes it 'unclear how to best advise organizational leaders.' Closes by identifying ethical voice as the field's most significant blind spot: because mainstream voice research has implicitly equated 'prosocial' with 'pro-organizational,' and because the standard measurement scales don't ask about raising misconduct, harassment, or fraud, the literature has had surprisingly little to say about exactly the situations, evoked directly by #MeToo and cases like Enron and Wells Fargo, where people knew and stayed silent anyway.
