The short answer: psychological safety is strongly associated with how employees experience work. In the American Psychological Association's 2024 Work in America survey of 2,027 employed U.S. adults, workers with higher psychological safety were far less likely to describe their workplace as toxic, while workers with lower psychological safety reported substantially more stress. The findings are associations from a survey, not proof that psychological safety alone causes every difference.
Psychological safety statistics at a glance
15% of U.S. workers described their workplace as somewhat or very toxic.
89% of workers who described their workplace as toxic also reported lower psychological safety.
Workers with higher psychological safety were 10 times less likely than those with lower psychological safety to describe their workplace as toxic: 3% versus 30%.
43% of U.S. workers said they typically felt tense or stressed during the workday.
That rose to 61% among workers experiencing lower psychological safety.
67% of workers reported at least one outcome in the previous month often associated with workplace burnout.
59% said their employer thinks the work environment is much mentally healthier than it actually is.
39% worried that disclosing a mental health condition to their employer would negatively affect them at work.
45% said they have to work more hours per week than they want to.
Workers with higher psychological safety were more likely to say they felt they belonged at work: 95% versus 69%.
Workers with higher psychological safety were also more likely to feel comfortable being themselves at work: 95% versus a substantially lower proportion among workers with lower psychological safety.
Among workers aged 18–25, 48% said people in their organization who were not close to their age did not see value in their ideas, compared with 16% among workers aged 65 and older.
Most of these figures come from one source: APA's 2024 Work in America survey. Keeping that clear matters. Twelve numbers from one survey are not twelve independent studies. They are different views of the same U.S. workforce sample and should be interpreted accordingly.
What is psychological safety?
Psychological safety describes a workplace climate in which people feel able to express concerns, ask questions, acknowledge uncertainty and discuss mistakes without expecting humiliation or retaliation. It does not mean that every idea must be accepted, that performance standards disappear or that employees are protected from disagreement.
For organizations, its importance is practical. Information is distributed unevenly. The person closest to a customer, process or emerging problem may know something a senior decision-maker does not. Whether that information enters the conversation depends partly on what the employee expects will happen after speaking.
1. Toxic workplace reports are strongly associated with lower psychological safety
APA found that 15% of workers characterized their workplace as somewhat or very toxic. Among this group, 89% also reported lower psychological safety. Looking at the comparison from the other direction, workers with higher psychological safety were ten times less likely than workers with lower psychological safety to describe their workplace as toxic: 3% compared with 30%.
This is a large difference, but the survey design does not establish that low psychological safety caused the toxic-workplace rating. The concepts also overlap: a workplace where people expect humiliation or retaliation is naturally more likely to be described negatively. The statistic is therefore most useful as evidence of a strong relationship, not a causal estimate.
2. Lower psychological safety is associated with substantially more stress
Across respondents, 43% said they typically felt tense or stressed during their workday. Among workers with lower psychological safety, that figure increased to 61%.
Again, the direction of causality cannot be established from this comparison. A difficult workplace may simultaneously produce stress and make speaking up feel risky. A stressed employee may also experience workplace interactions differently. What the data show clearly is that the two conditions frequently occur together.
3. Burnout-related experiences are widespread
APA reported that 67% of workers had experienced at least one outcome during the previous month often associated with workplace burnout, including low energy, lack of interest or motivation, loneliness or isolation, or reduced effort at work.
This statistic should not be interpreted as saying that 67% of U.S. workers had clinical burnout. APA describes these as outcomes often associated with burnout. That distinction is important because lists of workplace statistics frequently lose such qualifications when figures are repeated elsewhere.
4. Employees and employers may see workplace mental health differently
Fifty-nine percent of employed adults said their employer thinks the work environment is much mentally healthier than it actually is. Meanwhile, 39% worried that telling their employer about a mental health condition would negatively affect them in the workplace.
For leaders, the interesting issue is the information gap. A management team may genuinely believe an environment is supportive while employees make a different assessment based on everyday consequences. Formal policies and stated values tell people what the organization intends. Repeated experience tells them what is actually safe.
5. Psychological safety is associated with belonging
APA reports that workers experiencing higher psychological safety were more likely to say they felt they belonged at work: 95% compared with 69% among workers with lower psychological safety. Higher-psychological-safety workers were also more likely to say they could comfortably be themselves at work.
Belonging and psychological safety are related concepts, so the association is not surprising. Still, it reinforces the broader point that employees evaluate workplace safety through repeated social interactions, not only through formal reporting channels.
6. Age can affect whether employees believe their ideas are valued
APA's survey also examined intergenerational work. Overall, 32% of U.S. workers said people in their organization who were not close to their age did not see the value in their ideas. Among workers aged 18–25, the figure was 48%, compared with 16% among workers aged 65 and older.
At the same time, 92% of working adults said they appreciated the opportunity to work with people of different ages, and 87% said having employees from a range of age groups was an advantage. The findings therefore do not support a simple story of generations being unable to work together. They suggest that many workers value age diversity while some, especially younger workers, still feel their contributions are discounted.
What should leaders take from these statistics?
Psychological safety is sometimes reduced to telling employees to speak up. That puts the burden in the wrong place. Employees already make decisions about whether to speak based on what they observe: how disagreement is received, whether mistakes are used for learning or embarrassment, whether inconvenient information is welcomed, and whether challenging a senior person's view carries a social cost.
The useful leadership question is therefore not simply, “Have we told people they can speak?” It is whether the environment gives them reason to believe it.
About the data
The 2024 Work in America survey was conducted online in the United States by The Harris Poll on behalf of the American Psychological Association from March 25 to April 3, 2024. It included 2,027 employed adults and used weighting to align respondents with U.S. population proportions on several demographic variables. Because these are U.S. survey data, they should not automatically be generalized to employees in other countries. The comparisons described above are primarily associations and should not be presented as proof of causation.
