Approach your boss about meeting to discuss your salary. Keep communication in line with your normal exchanges. 2. During the meeting, keep the tone light, direct, and non-emotional (it's business, not personal!). 3. Arrive armed with documents backing your performance, but start with a verbal, top-line summary of your accomplishments, as well as any additional responsibilities you've taken on during your tenure. 4. Don't forget to position your case to appeal to their interests. And don't take for granted your boss is aware of all of your duties or successes. If your research indicates you're paid below market, mention that, too.
