Short answer: Emotional intelligence helps you notice what is happening, in you and in others, and respond deliberately instead of reacting. Under a toxic leader, that means recognizing manipulation early, staying calm when you are provoked, reading the dynamics in your team and setting boundaries clearly. But emotional intelligence is no shield on its own: manipulative leaders often have it too, and use it against others. Use it to protect yourself, not to endure more.
What emotional intelligence is
The term is used loosely. Research distinguishes between emotional intelligence as an ability, meaning perceiving, understanding and regulating emotions, and broader “mixed” models that also include personality traits such as motivation or social skills. A large meta-analysis found that the abilities build on each other: perceiving emotions comes before understanding them, which comes before regulating them, and the evidence on job performance depends heavily on which concept is measured (Joseph & Newman, 2010).
For practical purposes, four skills matter most when dealing with a toxic leader: self-awareness, regulating your own emotions, understanding others, and expressing yourself clearly.
How it helps under a toxic leader
1. Self-awareness: noticing manipulation early
Confusion after every conversation, guilt without a clear reason, tension before meetings with one particular person. These feelings are information. People who notice them early recognize patterns such as gaslighting sooner.
2. Emotion regulation: responding, not reacting
Toxic leaders often provoke reactions that they can then use against you: “You see how emotional you are.” Research distinguishes two common strategies. Reappraisal means looking at a situation differently (“This is about his insecurity, not my competence”). Suppression means keeping a straight face while boiling inside. People who reappraise more often experience fewer negative emotions and report better relationships and well-being; habitual suppression shows the opposite pattern (Gross & John, 2003). In the moment: pause, breathe, ask a question, answer later in writing.
3. Understanding others, without excusing them
Understanding why a leader behaves as they do, for example out of insecurity or pressure from above, can help you predict their behavior and not take it personally. It does not mean accepting it. Empathy is a tool for understanding, not an obligation to tolerate.
4. Reading the room
Who has influence, who are allies, where are the alliances? Toxic leaders often divide teams. Understanding the social dynamics helps you build support and avoid traps.
5. Assertiveness: expressing needs and limits clearly
Emotional intelligence includes the ability to say what you need without becoming passive or aggressive: “I need the information by Wednesday to meet the deadline.” More in assertiveness and effective communication.
The dark side: when the toxic leader is emotionally intelligent
Emotional intelligence is not automatically a virtue. Researchers have described how people can use it strategically for their own ends: to disguise their true feelings, to stir up emotions in others, or to control what others believe about them (Kilduff, Chiaburu & Menges, 2010). Many manipulative leaders are excellent at reading people. That is part of why they are so hard to see through, and why your own emotional intelligence works best as an early warning system, combined with documentation and allies.
A caution
“Be more emotionally intelligent” can turn into “adapt to the abuse”. If you find yourself constantly managing your boss’s moods at the expense of your own health, emotional intelligence is no longer the solution. Then it is about boundaries, escalation or leaving. See building resilience for more.
In the book: Chapter 9 of Breaking Free from Toxic Leadership, “Developing Emotional Intelligence and Communication Skills”, includes practical exercises. Chapter 10 covers the role of emotional intelligence in responding to manipulation.
