Emotional intelligence at work: what it is, how to build it
An evidence-led explainer on what emotional intelligence is at work, why it shapes how teams perform, and the habits that develop it.

Emotional intelligence is the ability to recognise emotions, in yourself and in other people, and to use that information to guide how you think and act. At work it is the difference between reacting to a tense moment and choosing a response to it. It is learnable, it can be measured, and it predicts how well people work together more reliably than most managers expect.
This article sets out what emotional intelligence is, why it matters for teams and the people who lead them, and the specific habits that develop it. It is written for professionals who manage people, not for specialists, so each idea is explained plainly first and named precisely second.
What emotional intelligence actually means
The term was defined by the psychologists Peter Salovey and John Mayer in 1990 and later popularised for a general audience[1]. The most useful working model at work divides emotional intelligence into four domains, split across two questions: is this about me or about other people, and is it about noticing or about acting.
Self-awareness and social awareness are about recognition: noticing what is happening emotionally. Self-management and relationship management are about regulation: doing something useful with what you notice. Most people are stronger on one side than the other, and the gap is where development effort pays off.
Why it matters for teams and managers
Technical skill gets an individual hired. How they handle other people decides how far a team gets. Emotional intelligence shows up in the ordinary moments that make or break collaboration:
- Giving feedback that lands as useful rather than as a threat.
- Staying steady in a disagreement instead of escalating it.
- Noticing when a colleague has gone quiet and checking in.
- Reading the room before pushing a decision through.
Between stimulus and response there is a space. In that space is our power to choose our response, and in our response lies our growth and our freedom.
A note on measurement
Emotional intelligence is measured in three broad ways, and they do not always agree[3]. Choosing the right one depends on what the result is for. A development conversation can use a self-report. A hiring decision needs something harder to game.
| Method | What it captures | Best used for |
|---|---|---|
| Self-report | How a person sees their own emotional skills | Reflection and coaching |
| Ability-based test | Performance on emotional problems with better and worse answers | Selection and benchmarking |
| 360-degree rating | How colleagues experience the person day to day | Development and calibration |
How to build emotional intelligence
Because emotional intelligence is a set of skills rather than a fixed trait, it responds to deliberate practice. The goal is not to feel less, but to put a small gap between feeling and acting, and to use that gap well.
A weekly practice for managers
- Name one strong emotion you felt at work, and what triggered it.
- Ask one colleague how a recent interaction landed for them.
- Delay one reactive message by an hour and re-read it before sending.
- Notice one moment where you chose your response rather than defaulted to it.
You cannot manage an emotion you have not noticed. Awareness is the whole first half of the skill.
Where teams get it wrong
Emotional intelligence is easy to talk about and easy to misuse. Three mistakes come up again and again:
- Treating it as being nice. Emotional intelligence includes delivering hard messages well, not avoiding them.
- Measuring it once and assuming it is fixed. It moves with practice, so a single score is a starting point, not a verdict.
- Using a self-report to make a hiring decision. People rate themselves generously, so match the method to the stakes.
