If you have had great performance in your job, then I would ask my immediate supervisor to speak with her superior for the raise particularly if other coworkers are getting raises, then maybe the time would be right.
Outline what you have done to save the company money or improve the workplace. Don't simply tell your boss you need a raise, because everyone does. Make yourself as valuable to the company as you can.
It's important to highlight the solid work performance history, special accomplishments, express satisfaction with current job, and indicate a strong desire to stay with the employer for years to come.
