Having a great letter of recommendation can make the difference between obtaining a raise and being denied a salary increase. An excellent letter of recommendation for a salary increase will highlight the candidate's job performance while asserting your authority as a personal and professional acquaintance.
Present the letter of recommendation in the standard business letter format. Place the date at the top of the letter, followed by the name of the recipient, title and address.
Use the introduction to state your professional acquaintance with the candidate and the purpose of the letter. State that you feel the candidate deserves a raise, listing the amount of time he has been employed since his last raise.
Describe a few examples that showcase your professional experience with the candidate. Use anecdotes that affirm the candidates most notable qualities and skills. In the process, you want to give a brief snapshot of the candidate's job performance history.
Explain the candidate's current salary and be specific about the increase in pay you feel the candidate deserves. It helps to have detailed numbers in the request.
End the letter with an affirmation of the candidate's loyalty to the company and the importance of the raise to ensure a strong relationship in the future.
Always sign the letter with a pen and in your own handwriting. Avoid electronic signatures such as email or scanned documents.
