When Feedback Crosses the Line: How to Behave

Most leaders believe that being direct and honest with negative feedback helps employees improve. And it can—when done thoughtfully. Our research shows, however, that when feedback comes across as belittling or humiliating, it often backfires, impairing performance rather than enhancing it.

In an online survey of 402 full-time U.S. employees, participants were asked to provide recollections of times when they received destructive criticism and what effects it had on them; 81% reported experiencing destructive feedback. Over 78% of these respondents described feedback so hurtful that they recalled it vividly, sometimes years later. While employees often remembered the performance issue itself, what lingered far longer was the emotional impact. Feelings of humiliation, shaken confidence, and loss of trust dominated their recollections, shaping how they behaved long after the incident had passed.

These emotional aftershocks carry real personal and organizational costs. In this article, we will share our findings about the ways destructive criticism shows up, who delivers it and why, and how it affects employees and organizations. Then, we will outline five practical ways leaders can deliver critical feedback without causing lasting harm, illustrated with concrete examples.

How Destructive Criticism Shows Up

Prior research has shown that employees are more likely to accept or reject critical feedback from supervisors depending less on the criticism itself than on how it is delivered—particularly whether it is perceived as fair and motivated by a desire to help rather than to blame. Building on this, our research identified five forms of destructive criticism stood out as uniquely harmful because they attacked the person rather than the behavior.

Feedback with no corrective instructions.

This was the most prevalent form of destructive feedback; 78% of respondents described such criticism as largely judgmental, offering little direction or guidance for improvement. For example, one person in our survey recalled: “She didn’t tell me what she expected of me or what I could have done better. She only berated me over a mistake. I went on to make the mistake several times more before I finally told her I needed to clarify what I was doing wrong. Only then did I learn.” Another person described the feeling this way: “It’s like they’re only seeing the bad stuff and not giving me any help to fix it. I walked out feeling pretty down, wondering if I was even doing anything right anymore. It’s tough when feedback feels more like a slap in the face than a helping hand.”

Feedback without guidance kills learning and doesn’t help people develop.

False or unfair criticism.

Around 67% of respondents described feedback they experienced as false or unfair. Employees described managers’ negative views as based on distorted or incomplete information about their performance. As a result, respondents felt wronged and undervalued, with their effort and expertise neither recognized nor respected. One person described it this way: “I was criticized for not doing things that I wasn’t asked to do in the first place.”

Rather than guiding improvement, inaccurate criticism undermines the credibility of both the feedback and the feedback-giver, leading employees to question the fairness of evaluation processes.

Dismissiveness or contempt.

Nearly 44% of the respondents described feedback delivered with an eye roll, a scoff, a dismissive tone, or even being yelled at. In these cases, it wasn’t necessarily the substance of the message but the way it was delivered that created the negative feelings. “He used a condescending tone and made me feel incompetent in front of my colleagues,” one employee recalled. Another described it this way: “His scoffing … made me feel like my concerns were unimportant. … The whole thing left me feeling like I couldn’t do anything right, which is a terrible feeling in a critical situation.”

Even without harsh words, a disrespectful tone or manner can turn otherwise valid feedback into destructive criticism.

Character attacks.

About 24% respondents reported feeling angry and demeaned when negative feedback sounded like an attack on their character or personality. These comments implied that the employee was fundamentally flawed. One employee said: “I was criticized for being lazy, late, and generally pretty useless.” Another recalled: “She told me I was the problem and a bully.”

Character-based criticism produces shame rather than learning. Shame, in turn, is paralyzing and undermines continuous performance improvement.

Public shaming.

Around 23% of respondents reported experiencing destructive criticism in public. Being criticized in front of others, during meetings, in email threads, or in group chats, was experienced as deeply damaging. As one employee recalled: “He criticized me in front of all my peers and also subordinates working under me. It felt really awful. He could have done so privately and not publicly.”

Public criticism doesn’t just hurt the receiver; it signals to everyone else that making mistakes aren’t safe, teaching them to stay silent when problems arise.

Who Delivers Destructive Criticism and Why It Matters

Destructive criticism can come from anyone with evaluative power, whether formal or informal. In our data, respondents described receiving such feedback from direct supervisors, senior leaders, peers, cross-departmental managers, subordinates providing upward feedback, and even external stakeholders such as customers or clients.

These sources, however, did not have equal impact. The most damaging experiences overwhelmingly involved direct supervisors, whose control over evaluations, assignments, and daily work made their criticism especially consequential. Feedback from senior leaders carried a different kind of weight: when executives delivered criticism harshly, employees interpreted it as a signal about the organization’s true values. As one respondent put it, if a vice president treated them this way, “this must be how the organization really works.”

Criticism from peers and coworkers tended to erode trust and collaboration within teams, a finding that echoes other research, while feedback from external stakeholders often left employees feeling exposed and unsupported, particularly when managers failed to intervene. Although cross-departmental managers and upward criticism from subordinates were less frequently cited, they could still contribute to negative experiences when delivered poorly.

What this shows is simple but important: destructive criticism is not confined to “bad bosses.” It is a broader organizational risk tied to how power is exercised at all levels.

What Destructive Criticism Does to People and Organizations

Destructive criticism is not just a momentary personal blow. It sets off a chain reaction that shapes how people behave, relate to others, and ultimately how they view the organization.

First, it shuts people down.

Criticism, especially when delivered publicly or out of proportion, often leaves employees feeling small, incompetent, or ashamed. These reactions quickly lead to withdrawal: people speak less in meetings, hesitate to ask questions, and grow cautious about sharing ideas. Over time, this withdrawal spreads. Employees become hyper-aware of mistakes, second-guess decisions, and avoid situations where they might be judged again. As experimentation declines and stretch assignments feel riskier, innovation and learning stall.

Second, destructive criticism pushes people toward the exit.

More than a third of respondents said their relationship with the feedback giver never fully recovered. Even when critics later softened or apologized, the incident lingered as a signal that this person was not safe. Once trust breaks, collaboration gives way to self-protection. Several respondents described the experience as a “workplace shock” that shaped their desire to leave. The resulting turnover increases recruiting and training costs, costs rarely traced back to everyday feedback practices.

Third, destructive criticism can redirect career trajectories, particularly early on.

A single episode was often enough to undermine confidence and alter how employees viewed their long-term potential. Instead of leaning into new responsibilities, they pulled back, questioned their abilities, and reassessed whether the organization was a place where they could grow. Over time, this quiet erosion of ambition weakens the leadership pipeline organizations depend on.

Finally, employees rarely interpreted destructive criticism as an isolated misstep

Instead, they saw it as a window into the organization’s true culture. Moments like these revealed whether stated values about respect, professionalism, or learning actually held under pressure. Culture is shaped not just by what leaders say, but by how people are treated in their most vulnerable moments, and destructive criticism leaves a deeper mark than most leaders realize.

Why People Deliver Destructive Criticism

Because our data come from recipients’ recollections, these explanations reflect how employees interpret the motivations behind destructive feedback rather than the givers’ conscious intentions or other drivers of the behavior. Across narratives, five common drivers emerged, none of which stem from malice:

Time pressure.

Stress can make managers snap or speak harshly, even when they don’t mean to. As one respondent put it: “He was overwhelmed, and I became the easiest place to dump frustration.”

Lack of training.

Many leaders experience discomfort when delivering negative feedback because they lack training in how to do so candidly and constructively. As a result, they tend to model whatever they have observed or experienced themselves.

Emotional leakage.

Criticism often emerges harshly when the giver feels anger, embarrassment, surprise, or anxiety about a failed task. In such cases, criticism becomes a way to regulate their own emotions, often unconsciously, rather than to support the recipient to learn and improve. Alternatively, destructive criticism can also arise from negative emotions the feedback giver is experiencing for reasons unrelated to the recipient’s performance.

Misbeliefs about employee motivation.

A large portion of destructive criticism reflects the belief that “hard truths” naturally stimulate motivation and build resilience. In reality, this approach often undermines engagement and learning.

Disguised discrimination.

Our analysis also revealed that certain employees were more likely to receive destructive criticism, with patterns linked to gender (often female), stature (petite), age (young-looking), limited experience (trainees or new employees), and race/ethnicity (those perceived as different from the norm at the workplace). For example, a male interviewee in a predominantly female profession observed similar dynamics, suggesting that bias can operate subtly and reinforce discriminatory treatment under the guise of negative performance feedback.

What Leaders Should Do Instead

Based on these insights, our research suggests five practices for preventing destructive criticism and promoting constructive learning cultures.

Start by setting clear guardrails for criticism.

Most organizations define what good feedback should look like, but far fewer articulate what feedback must never do. Leaders should be explicit that criticism should not humiliate, shame, punish, or attack someone’s character. When these boundaries remain implicit, feedback givers may justify destructive criticism as “being honest” or “holding people accountable.” Clear guardrails reduce ambiguity and set shared expectations for how feedback should be delivered in a constructive way.

Train leaders to use a simple three-part structure.

Identify a specific behavior, explain why it matters, and outline a clear next step. Without all three, feedback risks feeling like judgment. For instance, saying, “You’re not collaborative enough, and it’s frustrating the team,” labels the person without guidance. A better approach: “In the past two project meetings, you finalized decisions without inviting team input. This matters because it delayed the project by a week. Going forward, let’s reserve five minutes at the end of each meeting for team input before finalizing decisions.” Feedback tied to behavior, impact, and action helps employees improve and signals the goal is learning, not blame.

Slow down the moment of feedback.

Many destructive comments are not planned; they arise in moments of pressure, frustration, or surprise. A brief pause can make the difference. Before speaking, leaders can ask themselves whether they are reacting to a person or responding to a behavior, and whether the employee will leave the conversation knowing what to do next. If emotions are running high on either side, delaying the conversation is often the wiser choice. Even small pauses can prevent remarks that cause lasting harm.

Repair quickly when feedback goes wrong.

Not every feedback interaction will land as intended. When criticism causes harm, whether a leader delivered it or simply witnessed it, following up matters. Acknowledging the employee’s value, clarifying intent, and actively rebuilding psychological safety can prevent a single incident from becoming a lasting rupture. Repair is possible, but only when leaders recognize the harm and take responsibility for restoring trust.

Guard against bias disguised as feedback.

Our data suggest that destructive criticism often targets employees from protected groups, such as women, younger-looking staff, petite individuals, or those perceived as racially or culturally different. Periodically review whom you give critical feedback to, how often, and in what tone. Look for disparities across gender, race/ethnicity, age, or experience, and address them proactively. Check your standards: before giving feedback, ensure you are holding this person to the same job-relevant expectations you apply to others. Anchor comments in observable behaviors, results, shared performance standards, and specific examples. Focus on the work, not personal impressions. When in doubt, consult a peer or HR partner. Equally important is giving employees safe, confidential ways to seek clarification or raise concerns without fear of retaliation. Together, these practices shift feedback from threat to learning, focusing on performance improvement instead of reinforcing inequities.

. . .

Destructive criticism doesn’t just affect individuals. It signals to the entire organization what is safe, what is risky, and what leaders truly value. The culture people experience always matters more than the culture leaders proclaim.

Employees in our study were clear: they need feedback that develops without humiliating. When that happens, people don’t just perform better. They stay, learn, and invest in the organization’s future. That, ultimately, is what feedback is meant to do.
