The Importance of Assertive Leadership

If a leader cannot stand up for themselves or their team, they tend to get walked over, and so does the team. Budgets get raided, deadlines get squeezed, scope creeps in and nobody pushes back. Over time that wears people down and damages trust in the person meant to be looking after them.

Assertiveness goes the other way. By saying clearly what your team needs, what it can deliver, and where the limits are, you build credibility with people above you and with the people you manage. Most colleagues respect someone who can put their position across calmly, even when they disagree with it.

Being able to speak up about what you need, and what your team needs, is one of the more underrated parts of leading well. It lets people know where they stand with you and gives them the chance to either adjust their approach or push back with their own thinking. Without it, decisions get made on shaky information: managers above you assume your team has capacity it does not have, peers assume silence means agreement, and your own people are left guessing what you actually think of their work.

Good leaders use assertiveness to earn respect and hold authority without bullying anyone or shutting people out. It is a skill rather than a personality trait, which means most people can build it up with practice.

Assertive is not the same as aggressive

The two get muddled often, but they are not the same thing. Assertiveness is not about being loud, blunt to the point of rudeness, or talking over people. It is a straightforward, honest way of saying what you think, what you feel and what you need. Aggression, by contrast, tends to involve riding roughshod over someone else, whether that is by raising your voice, belittling them or simply refusing to acknowledge their position.

When you are assertive, you are trying to even out the power in a conversation rather than win it. Leaders who get this right are usually more interested in working out a solution that both sides can live with than in scoring points. That tends to produce better decisions and longer lasting agreements.

It also helps the relationships themselves feel more genuine. When you share an honest reaction to something, you give other people permission to do the same. That cuts down on the polite fiction that sometimes builds up in workplaces, where everyone nods in meetings and then complains privately afterwards. Telling someone honestly how their behaviour is landing also gives them a fair chance to change it, which a vague hint or a passive aggressive email simply does not do.

Plenty of people avoid being assertive because they are worried about causing conflict. In practice, staying quiet often causes more damage. You agree to an unrealistic deadline rather than challenge it, then miss it. You let a colleague keep cutting across you in meetings rather than name it, and your contributions get attributed to someone else. You sit on concerns about a team member's behaviour until it becomes a formal problem. Small issues turn into bigger ones, and you end up either exploding later or quietly disengaging.

What it looks like in practice

Assertiveness is partly what you say and partly how you say it. The simplest version is stating your view, opinion or feeling honestly and letting it stand. You do not need to dress it up or apologise for it, but you also do not need to hammer it home.

A softer version makes your point while acknowledging the other person's position. Something along the lines of "I can see why you'd want it done that way, but I'm not willing to sign off on it because of X." You are not caving in, but you are showing that you have actually listened.

Sometimes you may need to escalate. You begin with a straightforward statement of what you need, and if the other person ignores it or talks over it, you raise the intensity while staying calm. The aim is to make clear that the issue is not going away, not to start a row.

Occasionally you will hit a straight conflict, where your position and someone else's are flatly at odds. In those situations you have to be willing to say so directly. Pretending to agree, or fudging it, tends to store up trouble.

A few practical points worth keeping in mind:

• Set limits and stick to them. Backing down the first time someone pushes teaches people that pushing works.
• Be willing to say no. If you cannot take something on, or you do not agree with a decision, say so plainly rather than going along with it and resenting it later.
• Do not let guilt make your decisions for you. Saying no to one thing is often what allows you to do another thing properly.
• Watch your tone and body language. Steady voice, level eye contact and an open posture do a lot of the work for you.
• Give your reasoning briefly, then stop. Over explaining can make a firm position sound like a negotiation.

Building the habit

If assertiveness does not come naturally, it helps to think back over recent situations where you wish you had spoken up and reimagine them. Picture what you would say if you had your time again, how you would phrase it and what tone you would use. That kind of mental rehearsal makes it easier to find the right words when something similar comes up next time.

It is also worth getting feedback from people you trust. Most of us do not have a clear view of how we come across. A colleague or mentor can tell you whether you sound too soft, too sharp or about right. Ask specific questions rather than general ones: did I come across as clear about what I needed in that meeting, was there a point where I should have pushed back harder, did anything I said sound dismissive. Specific questions get you usable answers.

For people who find this genuinely difficult, organisations such as the Chartered Management Institute and ACAS offer guidance and training on workplace communication and managing difficult conversations, which can be a useful starting point.

Assertiveness is not a one off fix. Like most management skills it needs maintaining, particularly when you are tired, under pressure or dealing with someone more senior. The leaders who keep at it tend to find that their teams trust them more and that fewer problems fester in the background.
