They take credit and delegate blame
Successes are presented as their own achievements, while problems are attributed to others. Over time, the team loses its sense of recognition and trust.
29. 6. 2026 Insights Leadership and Management
A strong leader can inspire a team, while a toxic boss can gradually break it up. The difference between a visionary and a manipulative manager is often not obvious at first glance.
Recognizing the warning signs of toxic leadership can help protect your work, energy, and workplace relationships. After all, leadership is not only about results, but also about the way those results are achieved.
A narcissistic boss may not seem problematic at first. In fact, quite the opposite. Some traits associated with narcissistic tendencies can be perceived positively in the workplace, at least in the short term.
Such a leader often appears to be someone who:
In companies undergoing change or needing to respond quickly to market conditions, these qualities may seem like a major advantage. A highly charismatic individual can easily gain the attention of senior management and earn the trust of their team.
However, this is where the risk begins. Confidence is not automatically a sign of effective leadership.
A strong manager can inspire people while still giving them space to contribute. They can accept different opinions, admit mistakes, and recognize the contributions of others.
A leader with strong narcissistic tendencies, on the other hand, may constantly seek validation of their own exceptionalism and view disagreement as a threat to their position.
From a psychological perspective, the problem is not ambition or the desire to succeed. The risk emerges when the need for recognition outweighs responsibility toward the team.
Every leader makes mistakes. Every manager occasionally has to make unpopular decisions or set high expectations. That alone does not make someone a toxic leader.
The difference lies primarily in long-term behavioral patterns.
A demanding manager may expect high performance while still respecting their people. A toxic boss, by contrast, creates an environment where employees must adapt to their need for control or admiration.
In the workplace, it is important to observe specific behaviors: how a leader reacts to criticism, how they treat people, and whether they create a psychologically safe environment for collaboration.
Narcissistic leadership rarely reveals itself through a single incident. Instead, it appears through recurring patterns of behavior that affect the team, motivation, and overall work environment.
Successes are presented as their own achievements, while problems are attributed to others. Over time, the team loses its sense of recognition and trust.
Feedback is not seen as an opportunity for growth, but as a challenge to their authority.
People are divided into those who enjoy their favor and those who are more frequently criticized. This weakens collaboration and psychological safety within the team.
They expect others to follow rules that they themselves may ignore. As a result, decision-making becomes unpredictable.
Employees gradually stop speaking up because they fear negative reactions.
They give the team little room for autonomy and view delegation as a loss of control.
When employees would rather stay silent than share problems or ideas, one of the fundamental conditions of a healthy team disappears: psychological safety.

These signs alone do not necessarily mean that a leader is a narcissist. What matters is the long-term impact their behavior has on the team, communication, and workplace culture.
Narcissistic leaders may appear to be ideal candidates for leadership positions because of their confidence, charisma, and ability to make quick decisions. Companies sometimes mistake a strong presence for genuine managerial competence.
Short-term performance and the ability to drive change during crises can also play a role. A study by Nevicka et al. found that narcissistic leaders may be perceived as effective, while simultaneously reducing open information sharing within teams.
Professional boundaries are not a sign of unwillingness to cooperate. On the contrary, they help protect work quality, energy, and clear communication.
When dealing with a demanding or toxic boss, it can help to:
The purpose of boundaries is not to change another person’s behavior. Their purpose is to create a clearer framework for your own work and provide support through facts.
A demanding manager is not automatically a toxic one. The problem arises when humiliation, intimidation, abuse of power, or targeted pressure on employees become recurring patterns.
This may include bossing, meaning workplace bullying by a superior, as well as other forms of inappropriate behavior such as isolating employees, ridiculing them, or placing them under long-term unreasonable pressure.
A risky work environment may also involve psychosocial risks such as excessive stress, conflict, or lack of support.
In these situations, it is helpful to keep records, document specific incidents, and, depending on the severity of the issue, address it through HR, a higher-level manager, or professional support.
Leadership is not only about results, numbers, and the ability to drive change. True leaders also work with power, emotions, conflict, and responsibility for the people around them.
The ability to navigate emotions, conflict, and team relationships is what determines whether a manager becomes a genuine leader or simply someone with formal authority.
Future managers therefore learn not only how to make decisions, but also how to create environments where people can grow and communicate openly. These are the skills emphasized at NEWTON University through areas such as Psychology in management, Psychology for managers, or Business Leadership.
A leader’s strength is not measured by how much they can control others, but by how much they can help others grow.
A toxic boss is not defined by a single unpleasant incident, but by recurring patterns of behavior. Warning signs include belittling others’ work, shifting blame, manipulation, lack of respect, and creating an environment where people are afraid to speak up.
A diagnosis cannot be made based on workplace behavior alone. However, narcissistic traits may include a strong need for admiration, poor reactions to criticism, taking credit for others’ work, and a limited willingness to consider the needs of others.
It helps to keep communication factual, establish clear boundaries, confirm important assignments in writing, and maintain records of agreements. The goal is not to change the manager’s personality, but to protect your work and position.
Boundaries involve clearly communicating your capacity, priorities, and expectations. Helpful approaches include asking for priorities to be clarified or confirming assignments in writing to ensure mutual understanding.
If there is ongoing inappropriate behavior, bossing, bullying, harassment, or a situation that negatively affects the work environment, it may be appropriate to contact HR or a higher-level manager. Having specific examples and documentation is important.
A demanding manager may set high standards while still respecting and supporting their people. Toxic leadership is characterized by abuse of power, fear, manipulation, and a long-term negative impact on the team.
The difference between effective and toxic leadership is often not confidence or ambition. It lies in how a person handles feedback, responsibility, and the people around them.
A strong leader does not need to be right all the time. They need to hear reality. A narcissistic leader often does not seek solutions, but validation of their own exceptionalism.
The ability to accept different perspectives, admit mistakes, and give others space is what separates true leadership from a simple desire for control.
