Final answer:
When confronted with an aggressive person, the best initial action is to diffuse the situation by remaining calm, listening carefully, and focusing on collaborative problem-solving.
Step-by-step explanation:
When dealing with an aggressive person, the first thing you should consider doing is to diffuse the situation. This approach involves staying as calm as possible and actively listening to the other person's perspective. It is important to choose your words carefully to avoid escalating the situation further and to remain respectful and open throughout the interaction. By using open-ended questions, you can better understand the other person's point of view and also demonstrate that you are listening and value their opinion. Always focus on solving the problem collaboratively rather than assigning blame. If the situation cannot be resolved amicably, it may be necessary to seek assistance from a supervisor or the HR department.
