You've had it with your job, or you've found a new opportunity. Some companies may have policies about how to handle terminating your employment, but most employees simply give notice by writing a resignation letter. A Monster article notes: "The main goal of your letter is to inform your employer about the details of your resignation, but the underlying benefit is a chance for you to strengthen your relationship with your supervisor/colleagues and leave on a positive note."
Begin your resignation letter with a professional salutation. The standard is usually in the form of "Dear Mr. Smith:" or "Dear Ms. Brown:"
Announce that you are resigning from your position. Even if you are unhappy in your job and that is the reason you are leaving, write respectfully, using a phrase such as "Please accept this notice of my resignation. My last day will be (date)." or "It is with regret that I am tendering my resignation, effective (date)." Give your employer at least two weeks notice, as this is customary.
Start a new paragraph to provide your reason for leaving. For example: "I have accepted a position with ABC Corp. and will be starting my new duties on (date)." Other reasons include moving, starting school and medical concerns. Keep your explanation brief, and do not write emotionally.
Include a sentence about how helpful you will be in your remaining time on the job. For example: "I am happy to assist in any way to make this a smooth transition" or "I will make a list of my current projects and their status for your convenience."
Remember that the person or people receiving your letter may serve as one of your references in your career. In closing, thank the reader for the opportunity to work with her. Include a sentence such as "I know the skills I have acquired here will serve me well in the future."
End the resignation letter with "Sincerely," and sign your name.
Type your letter and proofread for errors.
A copy of this resignation letter will likely go into your personnel file. Therefore, if you ever return to this company, you will have left a good parting impression.
Don't write anything bad about the company or any employees, even if you are leaving under bad circumstances. Never burn bridges in your career.
