If my boss yelled at me during a meeting, I’d first take a step back to assess the situation. It's important to consider the context and whether this was a one-time occurrence or part of a pattern. Here’s how I’d handle it:

1. Stay Calm: I’d focus on staying composed in the moment and not reacting emotionally.

2. Reflect: After the meeting, I’d reflect on what happened. Was there any constructive feedback amidst the yelling? 

3. Communicate: I’d schedule a private conversation with my boss to discuss the incident. It’s crucial to express how it made me feel and seek clarity on any issues.

4. Evaluate: If this behavior is consistent and unresolved, I’d evaluate my options. Is this environment healthy for me? Are there opportunities for growth or improvement?

5. Decide: If the situation doesn’t improve, I’d consider looking for a new job where I feel respected and valued.

Ultimately, it’s about maintaining a professional environment where I can thrive.
