53% of workers say they have regretted not speaking up in a meeting, compared to 38% who regret having spoken up, according to Resume Now’s International Career Regrets Survey of 1,000 workers across the US, UK, France, and Germany. The gap is real but moderate — a 1.4:1 ratio that puts workplace voice closer to “balanced” than the lopsided inaction dominance seen in domains like travel or career risk-taking. A separate Zety survey of over 1,000 US workers found that 98% harbored some form of career regret, with women regretting not speaking up at a rate 34% higher than men.

The academic underpinning comes from Detert and Edmondson’s 2011 research on implicit voice theories — the taken-for-granted beliefs employees hold about when speaking up is risky or futile. Across 190 interviews and follow-up survey studies, they documented five distinct self-censorship rules that suppress voice even when the message would benefit the organization. The mechanism is straightforward: people default to silence because the social cost of speaking up (embarrassing a manager, being labeled a troublemaker) feels immediate and concrete, while the cost of silence (a problem festers, an opportunity evaporates) is diffuse and delayed. Gilovich and Medvec’s temporal pattern predicts exactly this: the sting of having spoken up fades as people rationalize or forget, but the nagging sense of “I should have said something” compounds over time.

The modest delta here deserves a caveat the flashier regret pairs do not need. Speaking up at work is not costless — 43% of employees fear retaliation for voicing concerns, and research shows that frequent or low-quality voice can lower status and performance ratings. This is one of the few domains where action regret holds non-trivial ground because the consequences of speaking up (a damaged relationship, a lost promotion) can be concrete and lasting. The directional finding still favors action, consistent with the broader regret literature, but the margin is narrow enough that blanket advice to “always speak up” would overstate what the data support.

    85% of employees reported situations where they felt unable to raise an issue to a supervisor despite believing it was important; the most frequent reason was fear of being labeled negatively
    抜粋
    “"85% of respondents said they had been in situations where they felt unable to raise an issue to a supervisor even though they felt the issue was important. The most frequently mentioned reason for remaining silent was the fear of being viewed or labeled negatively, and as a consequence, damaging valued relationships." ”

    Milliken, Morrison & Hewlin (2003), Journal of Management Studies 40(6), 1453-1476. Interviewed 40 full-time employees across diverse industries. The 85% figure establishes that the vast majority of employees have experienced the voice/silence dilemma. The fear of negative labeling explains why action regret (38%) is non-trivially high in this domain — speaking up carries real social risk that does not fade easily.

    抜粋

Survey measures across subsequent studies establish that these implicit voice theories are widely held and significantly augment explanation of workplace silence." ”

    Detert & Edmondson (2011), Academy of Management Journal 54(3), 461-488. This peer-reviewed study does not provide a single regret percentage but establishes the psychological mechanism behind self-censorship at work. It documents that employees routinely silence themselves based on taken-for-granted beliefs about hierarchy, even when speaking up would benefit the organization. Used as the theoretical anchor for why inaction regret in this domain is so prevalent.

    計算過程
    Zety survey of 1,000+ US workers. The 98% figure refers to overall career regret, not speaking-up regret specifically. The 34% gender gap highlights that not speaking up is disproportionately regretted by women. Used as corroborating evidence for the inaction-regret pattern.

注意事項

The core action and inaction rates (38% and 53%) come from the same Resume Now survey, which is a strength for direct comparison but a limitation in that the sample is self-selected career-site users — likely more career-engaged than the general population. The question asks about meetings specifically, not all workplace silence; regret about staying silent on ethical or safety issues may be substantially higher. Independent corroboration comes from three additional sources: Milliken, Morrison & Hewlin (2003) found 85% of employees had experienced the voice/silence dilemma; Crucial Learning's 2021 survey of 1,100 employees found 43% waste two weeks or more ruminating on unresolved problems; and the Zety 34% gender gap points in the same direction. The 1.4:1 ratio is modest by regret-pair standards; workplace voice is one of the few domains where action regret is non-trivially high, likely because speaking up carries real professional risk (retaliation, status loss) that does not fade as easily as other action regrets.
