What about a Job promotion request?

​Did your earlier push for promotion from your current job fail? Whatever the cause is, you can take three steps to engineer a brighter tomorrow for your career.
 
First – take an honest inventory of yourself as a candidate for promotion. What can you offer in a higher-level job, such as competencies, skills, judgment, and, most of all, profit-producing behaviors, to put yourself on a fast track with a promotion every couple years?
Second – conceptualize a plan by figuring out how you can magnify your strengths and correct any deficiencies.
Third – work your plan by drafting a statement with your persuasive facts onscreen or on paper.

Recommended things to say in a job promotion request
 
Keep the following points in mind when preparing your statement:

• In requesting a promotion, write of your capacity for growth and what you’re doing about it, such as taking extension courses, learning through online training, or tapping subject experts in your network.
• Fine-tune your timing. Commenting that a company expansion is on the horizon, noting that a promising new account has just come in the door, and observing that someone in your logical promotion path is about to leave the company are all examples of opportune times to make your pitch.
• A note of appreciation to an executive for allowing you to attend an industry seminar with your immediate boss is both appreciated and strategic.
• When asking for a promotion that would leave your current job vacant, mention that you’ve trained (or can train) one or more subordinates to seamlessly take over your job when you leave it. The message is clear: The work you accomplish for the company is being left in good hands when you’re elevated to the next level.

 
Not recommended things to say in a job promotion request
 
Never claim that you’re indispensable. Your bosses may decide that you’re too valuable where you are, that your departure would leave a void, and that you can’t be replaced.
 
Writing a formal request for promotion
 
Do not ask for an appointment, but instead hit the issue head-on with a letter to your manager asking for more responsibility and a higher-level position.
