Almost every business has at least one. The manager who delivers strong outcomes — revenue, projects, deadlines — but leaves a trail of unhappy, disengaged, or departed people behind them. 

They are often kept in role precisely because they produce results, with the people costs treated as an acceptable price.

This calculus is wrong — and increasingly expensive. The retention costs, the cultural damage, the flight of talent from their teams, the psychosocial risk exposure: the people costs of a manager with poor emotional intelligence consistently exceed the short-term output they deliver. The problem is that most businesses have never measured the people cost explicitly enough to see it.

 

What Emotional Intelligence actually means at work

Emotional intelligence in leadership is not about being nice or emotionally expressive. It is a set of measurable capabilities: self-awareness (knowing how your behaviour affects others), self-regulation (the ability to manage your own emotional responses under pressure), empathy (the ability to accurately read and respond to others’ emotional states), and social skill (the ability to build, influence, and navigate relationships effectively).

These capabilities correlate strongly with leadership effectiveness across a range of outcomes: team retention, psychological safety, innovation culture, and client relationship quality. A 2024 meta-analysis of leadership effectiveness studies confirmed that emotional intelligence is among the strongest predictors of long-term leadership success — consistently outperforming technical expertise after the first two years in role.

The reason most businesses do not develop it is not that they doubt its value. It is that they have no mechanism to measure it.

 

Making it measurable

Three steps to bringing EQ into your leadership development practice:

1. Include 360-degree feedback in your manager evaluation process.

Peer and direct-report feedback on leadership behaviours is the most effective mechanism for surfacing the emotional intelligence gaps that leaders cannot see in themselves.

2. Make the costs of poor emotional intelligence visible.

Track turnover at the team level. Track engagement scores by manager. Track the number of HR escalations and complaints. When the data is presented in context, the calculus changes.

3. Invest in development, not just assessment.

Emotional intelligence can be developed through coaching, structured reflection, and deliberate practice. Identifying a gap without offering a pathway to close it is not development — it is just labelling.

The leader who gets results but burns people is not a high performer. They are a performance liability with a delay. The sooner that is measured honestly, the sooner it can change.
