There are many ways to leave your job. You can stop showing up or you can inform human resources that you've quit. You can also draft a formal letter of resignation, which will preserve your right to collect unpaid salary and other benefits and may also give you the chance to obtain a reference letter for another job. Though most resignation letters are given with two weeks notice, there are times when circumstances force you to leave the same day you write the letter.
Use business format, and left justify your letter. Write the date followed by your name, the name of your immediate supervisor and the company name and address. Write the word "Dear," followed by the name of your supervisor. If you don't report to any single person, you can address the letter "To whom it may concern," or to the human resources department, if your company has one.
Write that you are resigning, effective immediately, and apologize for the short notice and inconvenience. Express the fact that though you know two weeks notice is customary, your circumstances will not allow you to fulfill that obligation. If you're under contract, you must request that your employer waive the notice period of resignation and allow you to leave immediately.
Express your willingness to be available to answer any questions about the work projects you are leaving behind, and if possible, identify a colleague who may be able to take over some of your duties. Thank your employer for the opportunity to have worked at the company.
Close the letter by writing, "Sincerely yours," or "Respectfully yours," and write and sign your name. Make a copy of the letter for your records.
Keep your letter short and concise. Express only what is necessary and avoid writing a detailed explanation that lists all the reasons you are leaving.
Avoid making accusations or using negative or angry words. Not only could your words be actionable under the law, but you'll destroy any chance of obtaining a reference letter.
If you're under contract, read the fine print to check if your employer has included penalties in the event that you leave without two weeks notice.
