Like My T-Shirt? It's Clean Today:
Put on your most professional front. Dress as though you are meeting an important client. Being bright and shiny in this meeting just emphasizes your grace under pressure. Be courteous, professional, confident and firm but keep a smile on your face. Your goal is not to antagonize your boss, but address her concerns and bring her around to your point of view.

Minimize Confrontation:
If you are very uncomfortable with confrontation, you may want to brief your boss ahead of time as to the topic of the conversation. That way she isn't caught off guard. Outline your requests and reasons in a memo, and then follow up in person. 

Behind Closed Doors:
Be sure that the interview with your boss is uninterrupted. Reserve time on her calendar and close the door.

If you have already prepped her by memo, then reiterate your strongest points. If this is the first time she's hearing about your request, then describe your agenda, and calmly and methodically take her through each of your sterling (and thoroughly researched) points.

After She Stops Laughing:
She will most likely say one of three things.

1. Thank you for reminding me, we have a cashier's check here for you in my drawer for back pay and a huge bonus. 
2. Things are tight right now, can we talk in 6 months? 
3. No way, not now, not ever and don't let the door hit you on your way out. 

So, of these possibilities, the most likely is number two. Best case scenario: your boss is impressed by your accomplishments and genuinely wants to help you. Sometimes she will scrape the bottom of her travel budget and offer you a minimal raise. Don't take it. If you've asked for 25% and she offers 10%, counter with 20%, etc. You will probably end up with 15% and feel grateful for the privilege because bosses are wily and sneaky that way.

Solve The Equation, Substitute For $:
At this point you pull out your "B" list of requests to help make up the difference. These include the little-known rebates, freebies, memberships, benefits, services and other little entitlements that are sometimes available. Tired of schlepping from the far side of the parking lot? How about a reserved space? Want to take every other Friday as a half day to coach your kid's Little League team or do volunteer work? Maybe she can relate and will support this community service. Oftentimes businesses trade services with each other and offer them as bargaining chips to their employees. See if they have deals with anyone. Feeling a little flabby? Ask if the company will pay for a gym membership in your neighborhood. If it's in the company's name, it might even be tax-free to you.

Delay Of Game:
If you get the infamous "This is a bad time financially" or "I'm not sure that will be approved", don't let the issue die there. Ask questions. When will the company be on steadier financial ground or when will the hiring/raise freeze end? Don't settle for "later". If your boss agrees that you deserve a raise, get the amount in writing including the date on which that raise will become effective. In the meantime, ask what additional responsibilities you can take on to justify your increase. Emphasize your desire for a win-win situation.

Keep The Company, Change The Job: 
If they tell you that you have capped out the salary for your pay-grade level. Ask for a promotion. Short of that, give specific hard examples of how your workload and contributions differ from those of your peers. Then ask for a different title. Once you're no longer saddled with "Coordinator" or "Director" you are free to move around the pay scale.

A Wooden Performance:
If she thinks your work performance leaves room for improvement then ask her what your weaknesses are. What can you do to improve those areas and make yourself indispensable? Are there any new projects coming up in which you can be involved and given a chance to shine? Figure out what her goals are and help her to achieve them. Look for a need and fill it.
