How to Request a Promotion
Talk to Your Manager. During your performance review or during a meeting with your boss, ask about opportunities for advancement. Mention you are seeking career growth for the future, but be sure to note that you enjoy your current position, so there are no hard feelings, regarding you moving on. Ask your supervisor if he or she can help with opportunities for promotion.
Check Open Job Listings. Most large companies and many smaller companies list job openings on the company website. Some positions may be open to internal candidates prior to being available for external applicants, so you'll have a jump on the competition. Check regularly for new listings and apply for jobs that are a good fit for your background and experience.
Follow the Application Process. Promotions may be handled through the company's standard hiring process. Which means you may have to apply for a promotion and compete with other applicants for the job. Don't presume that the hiring manager or department manager reviewing your qualifications will know your background. Take the time to update your resume and to write a targeted cover letter for the job you are interested in. Follow the application process, if there is a formal procedure for applying for internal job postings.
Request References. Ask your supervisor and other managers you've worked with for a letter of recommendation. References, especially from high level staff, carry a lot of weight. Here's a sample letter of recommendation for a promotion to review.
