Clear up any confusion. Clearly state your reasoning for quitting in the letter. You do not need to be overly harsh, but constructive criticism is always welcome in business. The last thing a manager wants to see is an employee leaving. Farewell message delivery upon your departure from the company will help clarify what your reasoning is for leaving your current position, and will help the manager understand how he or she can improve the working conditions of the company (if those are part of your reasoning). This will not only leave you satisfied (with a chance to get everything off of your chest), but will also provide the company with valuable feedback.
Include things that you liked about your job. This is key. When an employee is leaving, a farewell message can quickly turn into an unorganized list of negative aspects related to his or her experience at the company. This can leave you looking extremely pessimistic. Instead of focusing only on the negatives, show your employer that there are also enjoyable characteristics related to the position. This will cause your previous employer to take your considerations more seriously, and will maintain your reputation as a professional.
Do not let your emotions get the best of you. In the heat of the moment, it is easy to decide that you will berate your boss for treating you horribly and never listening to your suggestions. This will make you look foolish and immature, especially when quitting your job. Instead of acting upon your emotions, take a few days to thoroughly examine and edit your 2 week notice on paper. If your composition is high quality and presents good points, the boss will not simply view you as another employee leaving. A farewell message that is highly structured and well put together will receive more recognition than a last minute list of concerns that is hastily thrown together.
Give your employer the letter in person. Many people dread the idea of quitting in person; however, you will feel much better after the fact, and quitting in person allows for many unresolved issues to be discussed. In large companies, it is highly likely that an employee is leaving every day. Providing a farewell message in association with your one-on-one meeting will allow your boss to reference something in writing after you leave. This is extremely important if you hope to improve the conditions of your position for whoever will hold it next.
Thank your boss for the opportunity to work with the company. This can be hard to do, but you are the employee leaving. If your farewell letter and your time together discussing your reasoning for leaving the company also focus on your appreciation of the opportunities and compensation that you received during your employment, it will be much easier to leave the business looking like the "good guy". It is always tempting to laugh and emphasize that you feel as though you wasted your time, but taking the high road is much more honorable (and won't come back to bite you).
As an employee, leaving your company can be difficult. Combining a farewell message with a one-on-one meeting is the most effective way to communicate with your employer, and quit your current job on good terms with everyone at the company.
