Explain how to negotiate a salary increase with your manager

Response A

Just ask for more money. Tell them you deserve it and you'll leave if they don't give it to you.

Response BSelected

Start by researching market rates for your role using sites like Glassdoor or Levels.fyi. Document your key accomplishments and quantifiable impact over the past year. Schedule a dedicated meeting with your manager, present your case professionally, and be prepared to discuss specific numbers while remaining open to negotiation on timing or additional benefits.

Evaluation Reasoning

Response B provides actionable, professional advice with specific resources and a clear framework. Response A is confrontational and lacks practical guidance that could damage professional relationships.
