Letters of recommendation are a valuable commodity when someone is searching for a job that fits him perfectly. If a coworker requests a letter of recommendation and you want to help her out, you can write a favorable letter that states the reasons you think she would do well in the new position. Your letter of recommendation could be the difference of whether your coworker gets the new job or promotion.
Place nice letterhead or professional-looking business paper in the printer. A letter of reference should get printed on the same type of paper that you would use for a resume or a letter from your office.
Introduce yourself in the first paragraph and write about how you met and how long you have known the person whom you are writing a recommendation for. Mention the company that you both worked for and in what positions the two of you worked. You can also write down how often the two of you worked together, if you so choose.
Write down the coworker's qualities that you admire and why you would recommend him for the position that he is applying for. Discuss any awards that the coworker achieved and mention if the coworker frequently volunteered for overtime or extra duties.
Close the letter of recommendation with a summary of why you valued your coworker on the job, and offer your contact information for the prospective employer.
