Advocating for a pay increase can be approached from several angles using the insights from the provided excerpts. Here are some strategies based on the writings of Ed Batista:

1. Demonstrate Commitment Over Compliance: As per "Compliance vs. Commitment (On Behavior Change)," showing that you are not just complying with the minimum requirements but are genuinely committed to the company's goals can be a powerful argument. Emphasize the ways in which you have taken initiative and exceeded expectations. Committed employees who derive fulfillment from their work are more likely to persist in the face of difficulties, which is valuable to any organization.

2. Highlight Intrinsic Motivation: According to Herzberg's research, intrinsic motivators such as achievement, recognition, responsibility, and growth are key to job satisfaction ("Currencies (On Motivating Different People)"). If you can show how your work aligns with these factors and how a pay increase would support your continued growth and achievement, you may present a stronger case.

3. Understand Your Value and Currencies: In "Currencies (On Motivating Different People)," various forms of value or 'currencies' are listed that employees might find motivating. Understanding which of these currencies apply to you and how they relate to your request for a pay increase can strengthen your argument. For example, if recognition or status is important to you, discuss how a pay increase reflects the recognition of your contributions and achievements.

4. Prepare for One-on-Ones: "How to Have Better One-on-Ones" suggests that employees should own the agenda in these meetings. Use this opportunity to discuss your contributions, achievements, and the value you add to the company. Make sure to prepare your case well, including any supporting materials or data that demonstrate your impact on the company's success.

5. Express Your Needs Clearly: In your one-on-one discussions, as suggested by Claire Hughes Johnson, ensure that you are clear about what you want and why it matters to you ("How to Have Better One-on-Ones"). Be prepared to articulate how a pay increase is not just about the money but also about what the money represents in terms of your personal and professional goals.

6. Engage in Dialogue: Building commitment through dialogue is essential ("Compliance vs. Commitment (On Behavior Change)"). Use your one-on-one time to engage in a meaningful conversation about your role, expectations, and how a pay increase aligns with your mutual goals for your position and the company.

7. Be Ready to "Disagree and Commit": If your initial request isn't met with agreement, be prepared to use the principle of "disagree and commit" to continue the conversation and work towards a mutually agreeable solution ("Compliance vs. Commitment (On Behavior Change)").

Remember, advocating for a pay increase is about demonstrating your value to the company, showing how your motivations align with the organization's goals, and being prepared to have a constructive and open dialogue with your supervisor.
