Conflict is inevitable in any workplace. Wherever people with different goals, priorities, and personalities work together, friction will appear. What separates high-performing teams from struggling ones is not the absence of conflict, but how skillfully that conflict is handled. The Thomas Kilmann Conflict Model gives managers and HR professionals a clear, practical map for navigating those moments.
Developed by Kenneth W. Thomas and Ralph H. Kilmann in the 1970s, the model underpins the Thomas Kilmann Conflict Mode Instrument (TKI), one of the most widely used conflict-assessment tools in the world. Rather than labeling any one approach as 'right' or 'wrong', the model recognises that effective people choose different responses depending on the situation.
The framework is built on two dimensions of behaviour. The first is assertiveness: the degree to which you try to satisfy your own concerns. The second is cooperativeness: the degree to which you try to satisfy the concerns of others. Plotting these two dimensions against each other produces five distinct conflict-handling modes.
1. Competing (assertive, uncooperative). The competing mode is power-oriented. You pursue your own concerns at the other person's expense, standing firm for what you believe is right. This style is useful in emergencies, when an unpopular but necessary decision must be made quickly, or when you need to protect yourself against people who take advantage of non-competitive behaviour. Overused, however, it can leave others feeling steamrolled and discourage honest feedback.
2. Collaborating (assertive, cooperative). Collaborating is the opposite of avoiding. You work with the other person to find a solution that fully satisfies both sets of concerns. It involves digging beneath the surface to understand the underlying needs of each party and creating an outcome that would not have been possible alone. Collaboration is ideal when the issue is too important to compromise, when you need buy-in, or when you want to merge different perspectives. Its main cost is time, so it isn't suited to trivial or urgent matters.
3. Compromising (moderate assertiveness, moderate cooperativeness). Compromising sits in the middle. The goal is a mutually acceptable solution that partially satisfies everyone, splitting the difference, exchanging concessions, or finding a quick middle ground. It works well when goals are moderately important, when two parties of equal power are committed to mutually exclusive positions, or when you need a temporary settlement under time pressure. The risk is that no one is fully satisfied, and important concerns may be glossed over.
4. Avoiding (unassertive, uncooperative). When avoiding, you neither pursue your own concerns nor those of the other person, you sidestep, postpone, or withdraw from the conflict. While it sounds negative, avoiding can be the right call when an issue is trivial, when emotions need time to cool, when the potential damage outweighs the benefits of resolution, or when others can resolve the matter more effectively. Used too often, though, it allows problems to fester and decisions to drift.
5. Accommodating (unassertive, cooperative). Accommodating is the opposite of competing. You set aside your own concerns to satisfy the other person, showing generosity, deference, or a willingness to yield. It is appropriate when you realise you are wrong, when the issue matters far more to the other person, when preserving harmony is especially important, or when you want to build social credit for later. Over-relying on it, however, can mean your own valid needs and ideas go unheard.
The central insight of the Thomas Kilmann model is that no single mode is best. Each style is effective in some situations and counter-productive in others. The most capable managers develop the flexibility to read a situation and consciously select the right mode, rather than defaulting to the one that simply feels most comfortable.
In practice, most people have one or two preferred modes they rely on under stress. A manager who instinctively competes may win arguments but erode trust; one who habitually avoids may keep the peace while problems quietly compound. Awareness of your own default is the first step toward expanding your range.
For HR and L&D leaders, the model is more than a theory, it's a development tool. Building conflict competence across an organisation reduces escalations, protects working relationships, and supports a culture of psychological safety. It aligns directly with a preventive approach to human skills: equipping people to handle disagreement constructively before it turns into attrition, disengagement, or costly disputes.
To apply the model with your teams, start by helping people identify their natural conflict style and the situations where it serves them well or holds them back. Then practise matching the mode to the moment: collaborating on high-stakes decisions, compromising when time is short, accommodating to preserve a key relationship, competing when safety or principle is at stake, and avoiding when the issue genuinely isn't worth the energy. With deliberate practice, conflict shifts from something teams fear to a skill they can wield.
Ultimately, the Thomas Kilmann Conflict Model reframes conflict as a normal, manageable part of working life. By understanding the five conflict management styles and developing the judgement to choose between them, managers and HR professionals can turn tension into a catalyst for stronger relationships, better decisions, and healthier workplace cultures.
