Toxic leadership: signs, costs and what to do

Toxic leadership is not a bad day or a demanding boss. It is a repeated pattern in which a leader's behavior damages the people around them and the work itself, and it shows up first in employee engagement data, long before it shows up in exit interviews. U.S. Army doctrine now calls it counterproductive leadership: leader behaviors that violate the Army's core leader competencies or Army Values and prevent a climate in which the mission can be accomplished. Its doctrine notes that the word "toxic" was used for leaders who engaged in exactly these behaviors.

Research on companies points the same way. In an MIT Sloan Management Review analysis, the leading elements of toxic cultures were a failure to promote diversity, equity and inclusion; workers feeling disrespected; and unethical behavior. Leaders set those conditions, which is why toxic culture and toxic leadership are so often the same problem.

Every manager has bad days. The Army draws the line clearly: infrequent or one-time negative behaviors do not define counterproductive leadership, but recurrent negative behaviors do, and so can a single serious act that damages performance and people's welfare. That gives a useful test for any workplace. Ask three questions: Does it repeat? Do different people describe it in the same way? Would it be unacceptable even once, such as a threat or a lie to a customer? A yes to any of them deserves attention.

ADP 6-22 organizes counterproductive leadership into broad categories to help organizations identify and address it. They translate well to civilian workplaces:

A leader can show more than one pattern, and the categories overlap. Ineffective leadership is the odd one out: it is often a skill problem rather than a character problem, which matters for what you do next.

No single act makes a leader toxic. Look for patterns that repeat and that people describe in similar terms:

• Disrespect: belittling people in meetings, public blame, sarcasm aimed at individuals.
• Intimidation: threats about jobs or reviews, punishing disagreement, making people afraid to report problems.
• Self-serving decisions: taking credit for the team's work, shifting blame down, protecting status over results.
• Erratic standards: rules that change with the leader's mood, favorites who are exempt.
• Ethical shortcuts: pressure to bend rules, hide mistakes or mislead customers.
• Team symptoms: silence in meetings, people avoiding the leader, rising sick days and a stream of transfer requests and resignations.

The clearest cost is people leaving. An MIT Sloan Management Review analysis of the Culture 500 companies found that a toxic corporate culture was 10.4 times more powerful than compensation in predicting a company's attrition rate compared with its industry. SHRM estimated in 2019 that turnover due to workplace culture may have cost U.S. organizations as much as $223 billion over the previous five years. In the same survey, nearly one in five employees had left a job because of its culture in the past five years, and 49% had thought about leaving their current organization.

The human cost is just as real. In the American Psychological Association's 2023 Work in America survey, 19% of workers said their workplace was very or somewhat toxic. Those workers were more than three times as likely to report harm to their mental health at work as those who did not describe their workplace as toxic: 52% compared with 15%.

Research on individual supervisors shows the same damage at a smaller scale. In Tepper's study of abusive supervision, subordinates who saw their supervisors as more abusive were more likely to quit; those who stayed reported lower job and life satisfaction, weaker commitment, more conflict between work and family and more psychological distress. Army doctrine reaches the same conclusion from its own experience: counterproductive leadership can lower task performance and well-being and increase depression and burnout.

People rarely quit a company in the abstract. They leave the daily experience their manager creates. Gallup's research shows that managers account for at least 70% of the variance in employee engagement scores. In a separate Gallup study of 7,272 U.S. adults, one in two had left a job to get away from their manager at some point in their career. One toxic leader can therefore undo much of what an organization invests in its culture, and one good leader can protect a team from a difficult wider environment.

That is also why toxic leadership persists. A leader who hits short-term targets can look successful from above while the team below pays the price. Unless the organization measures how people experience their manager, the problem stays invisible until resignations arrive.

High standards are not toxic. Many of the best managers people remember were demanding. The difference shows in how the same situations are handled:

The test is what people feel after a hard conversation: clear about what to do next, or afraid. Giving feedback the right way is one of the clearest dividing lines.

It depends on the pattern. Leaders whose harm comes from missing skills, such as vague expectations, avoiding conflict or never giving recognition, often improve with coaching, specific behavioral goals and upward feedback that shows whether anything changed. Leaders who bully, retaliate or break rules rarely change through training alone, and every month they stay teaches the team that the behavior is accepted.

Whatever the pattern, change has to be visible to the people affected. Set a short review period, measure it through the team's own feedback rather than the leader's account, and decide in advance what happens if the behavior continues.

1. Measure it where it happens. Run regular anonymous engagement or pulse surveys and report results by team, with a minimum group size so no answer can be traced. Sudden drops in one team are a signal worth a conversation.
2. Ask upward. Add upward and 360-degree feedback to leader reviews, so the people a manager leads have a voice in how that manager is assessed.
3. Give people a safe channel. Make it clear how to raise a concern outside the reporting line, and protect people who do it from retaliation.
4. Hire and promote for behavior, not only results. Define how leaders are expected to treat people, and weigh it in promotion decisions as heavily as targets. Our guide to what makes a good leader shows how to assess character alongside competence.
5. Act on evidence. Coaching helps leaders who lack skills. Persistent abuse, intimidation or ethical violations call for consequences, or the rest of the organization learns that the behavior is acceptable.
6. Check your own habits. Senior leaders model what is tolerated, and a team that has worked under a toxic leader needs a deliberate plan to rebuild trust in the workplace. Ask your own team what you should start, stop and continue doing, and practice the habits of humility in leadership: admit mistakes and credit others by name. Make the standards you ask of others visible in your own record; integrity in leadership gives a weekly routine for keeping and renegotiating commitments.

Keep a dated, factual record of incidents: what happened, who was present and what was said. Stick to observable facts and leave out labels, so the record holds up when someone else reads it. Keep copies of your own work, instructions you received and the outcomes, in case your performance is questioned later. Use the channels your organization provides, such as your manager's manager, HR or an ethics line, and ask how your concern will be handled. If your health is affected, use the support your employer or health plan offers. For questions about your legal rights at work, an employment lawyer or your state labor department can advise you. Talk to colleagues you trust, too: patterns are easier to address when several people describe the same behavior, and support from peers makes a hard period easier to get through.

Software cannot fix a leader, but it can make patterns visible sooner and give people a safer way to speak up. Engagement platforms run anonymous surveys and show results by team and manager; performance tools add upward and 360-degree feedback to reviews. If you are comparing tools, start with the highest-ranked employee engagement platform and what it costs, and check its anonymity thresholds, manager-level reporting and how it helps managers act on results.
