Answer:
Avoid becoming too emotional and focus on facts.
Step-by-step explanation:
It is important for Joel to remain calm and professional when addressing the situation, and to focus on presenting the facts of the situation in a clear and objective manner. Being too emotional or aggressive in the moment will only detract from the legitimacy of his claims. He should also avoid destructive or retaliatory actions, as they will only make the situation worse. Instead, it is better to speak with his supervisor after the meeting to explain the situation, and provide evidence of his contributions to the project.
