Do you dare to say 'no' when your schedule is overflowing? Do you speak your mind in a meeting, even if it differs from the rest? Being assertive is a skill that many professionals find difficult, but one that makes the difference between working effectively and constantly letting your boundaries be crossed. In this article, you will discover exactly what assertiveness entails, why it is indispensable in the workplace, and how to develop it step by step.
What does being assertive mean?
Assertiveness is the ability to stand up for yourself in a direct, honest, and respectful way. It lies exactly between two extremes: passive behavior (always going along with things, not setting boundaries) and aggressive behavior (dominating others, not giving space). An assertive person is clear about what they want, feel, and think, without hurting or belittling the other person.
In the workplace, assertiveness manifests itself in everyday situations. Think of give feedback and receive without becoming defensive. Or set boundaries when under excessive work pressure. Clearly communicate what you need from colleagues or supervisors. And take a stand in a meeting, even under pressure.
Assertive behavior versus passive and aggressive behavior
To properly understand assertiveness, it helps to compare it to the two other communication styles you encounter in practice.
Passive behavior You can recognize this by their avoidance of conflict. Someone who communicates passively rarely says what they really think, agrees with everything, and swallows their frustrations. In the short term, this seems to maintain a good atmosphere, but in the long run, it leads to accumulated irritation, stress, and the feeling of not being taken seriously.
Aggressive behavior is the other extreme. Here, one's own opinion takes center stage, without regard for others. Aggressive communication is often accompanied by a raised voice, accusations, and the disregard of others' needs. The result: colleagues who shut down, resistance, and damaged working relationships.
Assertive behavior It lies exactly in between. You are clear about your position and boundaries, but you also listen to the other person. You express your opinion without damaging the relationship. The difference from aggression lies in respect: assertive communication always takes the other person's position into account.
There is a fourth style that is often overlooked: passive-aggressive behaviorThink of sarcasm, intentionally delaying tasks, or giving compliments that are actually veiled criticism. This behavior often arises when someone does not dare to speak up assertively, but the frustration still seeks an outlet.
Why is assertiveness important for managers and professionals?
Research shows time and again that assertive employees experience less stress, maintain better relationships, and perform more effectively. For managers, assertiveness is indispensable: those who cannot express themselves clearly lose authority and control. Employees need a manager who is clear, not someone who approves of everything or, conversely, dictates everything.
In practice, you see that assertive leaders are better able to:
- Clearly setting expectations without micromanagement
- To have difficult conversations (think of performance reviews or performance reviews)
- To identify and resolve conflicts early
- To create a safe team culture where everyone dares to speak up
- To make decisions and stand behind them
Moreover, assertiveness is closely linked to self-confidence. Those who communicate assertively show that they know and respect their own position, and invite others to do the same. leadership training developing assertiveness is therefore a recurring theme.
The science behind assertiveness
Assertiveness has strong roots in psychology. The American psychologist Andrew Salter laid the foundation in the 1940s with his work on conditioning and self-expression. Later, Joseph Wolpe and Arnold Lazarus built upon this with concrete assertiveness training.
The core idea is simple: assertive behavior is learned and can therefore be relearned. People who learned as children to keep their mouths shut or that conflicts are scary have often developed a passive communication style. But that style is not fixed. With conscious practice and the right techniques, you can become more assertive, regardless of your starting point.
Recent research shows that assertiveness is directly related to emotional intelligence. People who recognize and regulate their own emotions well find it easier to communicate assertively. They react less from an automatic reflex (fight, flight, or freeze) and more from a conscious choice.
How to become more assertive? 7 practical steps
1. Know your own boundaries and needs
Assertiveness begins with self-knowledge. What is important to you? Where do you draw the line? If you don't know this, you cannot communicate it. Regularly take the time to reflect on situations that drain your energy or where you think afterwards: “If only I had said something.” Write these moments down. Recognizing patterns is the first step toward change.
2. Use 'I' messages
Formulate your message from your own perspective: “I find it difficult when meetings run over” works better than “You never stick to the time.” I-messages are less accusatory and evoke less resistance, increasing the likelihood of a constructive conversation. The structure is simple: “I [feel] as [situation], because [reason]. I would like that [request].”
3. Practice with small situations
Assertiveness is a muscle that needs to be trained. Don't start immediately with the most difficult conversation, but practice in everyday situations. Return an order if it is incorrect. Indicate if you disagree with something in a team meeting. Ask for clarification if you don't understand something. Every small step builds self-confidence.
4. Learn to say 'no' without feeling guilty
Saying 'no' is not a rejection; it is a choice based on your own priorities. An assertive 'no' doesn't need to contain an extensive explanation. Short, direct, and friendly: “I have too much on my plate right now; I can't take this on.” That is sufficient. Practice sentence for today: say 'no' today to something you would normally say 'yes' to.
5. Pay attention to your body language
Assertiveness is not just about words. Your body language reinforces or undermines your message. Make eye contact, stand or sit upright, and speak at a calm and steady pace. Avoid crossing your arms (this comes across as defensive) and looking away (this signals insecurity). Congruent communication (words and body language aligned) makes your message credible.
6. Prepare for difficult conversations
You don't have to be assertive on the spot. In situations that you know will be difficult (a conflict with a colleagueFor a negotiation with a client, it pays to prepare. Write down what you want to say. Consider possible reactions from the other person and how you can respond to them. This preparation reduces tension and increases your self-confidence.
7. Accept that not everyone likes it
People who are used to you always going along with things will sometimes react with surprise or even irritation when you become more assertive. That is normal. Assertiveness is not meant to please everyone. It is meant to communicate honestly and respectfully, even when it is uncomfortable. Relationships that can handle this ultimately become stronger.
Assertiveness in the workplace: common situations
Let's make the theory concrete with situations you recognize as a manager or professional.
You get an extra project on your plate while your schedule is already full. Passive response: “Yes, I’ll do that.” Aggressive response: “Forget it, I already have enough to do.” Assertive response: “I understand that this project is a priority. Right now I am working on X and Y. I can take this on if we decide together what can be shifted around.”
A colleague repeatedly delivers late. Passive reaction: taking over the work yourself and saying nothing. Aggressive reaction: “You are always late, it is impossible to work with you.” Assertive reaction: “I notice that the deadline has been missed the last three times. That is impacting my schedule. Can we discuss how to resolve this?”
Your supervisor asks you to work overtime on an evening when you have appointments. Passive response: canceling your plans. Aggressive response: getting angry about the question. Assertive response: “I already have an appointment tonight. I can start early tomorrow morning to finish it. Does that work too?”
Common mistakes when communicating assertively
Assertiveness sounds simple in theory, but in practice, things often go wrong. These are the most common pitfalls.
Explaining too much. Anyone unsure about saying 'no' tends to endlessly justify why. That undermines your message. Keep it short and concrete.
Using assertiveness as a weapon. Some people use assertive techniques to get their way. That is not assertiveness; that is disguised aggression. Assertiveness is always accompanied by genuine interest in the other person's perspective.
Only be assertive when it is easy. The real test of assertiveness comes not from your intern, but from your director. Consistent assertive behavior, regardless of hierarchy, makes you credible.
Forgot to listen. Being assertive does not mean that you are always doing the talking. Listening carefully to the other person is an essential part. Ask questions, summarize, and show that you understand the other person before stating your point of view.
Developing assertiveness through training
Do you want to structurally strengthen your assertiveness? In the leadership training courses by Kenneth Smit You learn how to communicate clearly with self-confidence. You practice with realistic case studies, receive personal feedback, and develop a style that suits you.
Also our communication training pay extensive attention to assertive conversation. And in the sales training You will learn how to negotiate assertively and conduct client conversations without losing your position.
Assertiveness is not an innate trait, but a skill you can learn. With the right techniques, awareness, and practice, you grow in your ability to communicate clearly, honestly, and respectfully. And that has a direct impact on your work relationships, your performance, and your job satisfaction.
Assertive behavior is standing up for yourself in a direct, honest, and respectful way. It is the middle ground between passive behavior (always going along with things) and aggressive behavior (dominating others). You are clear about your wishes, feelings, and boundaries, without hurting the other person.
You become more assertive by learning to recognize your own boundaries, using "I" messages, practicing in small situations, paying attention to your body language, and learning to say "no" without feeling guilty. Training and coaching can significantly accelerate this process.
Assertive behavior is clear and direct, but also respects the other person. Aggressive behavior ignores the interests of the other person and is aimed at dominance. The difference lies in mutual respect: assertiveness seeks a solution for both parties, while aggression primarily wants to win.
Assertive leaders set clear expectations, conduct difficult conversations, and create a safe team culture. Without assertiveness, you lose authority and direction as a manager. Employees need clarity, not someone who approves of everything or dictates everything.
Yes. Assertiveness is a learned skill, not a personality trait. With conscious practice, the right techniques, and possibly guidance through training, you can become more assertive, regardless of your current communication style.
