A Bonus Letter is a document that employers use to provide a bonus to an employee. This type of letter is usually issued after an employee has achieved a specific milestone or goal, such as completing a project, surpassing a sales quota, or meeting a deadline. Bonuses can come in the form of cash or other rewards, such as additional vacation days. There are two main types of Bonus Letter: a formal bonus letter that is written and signed by an employer, and an informal bonus letter that is written by an employee to request a bonus. A formal bonus letter typically includes the employee's name, the date of the bonus, the amount of the bonus, and the reason for the bonus. It may also include any additional information about the bonus, such as terms and conditions or restrictions. An informal bonus letter is typically written by an employee to request a bonus. This type of letter should include the employee's name, the date of the request, the reason for the request, the amount of the request, and any supporting evidence. It should also include a request for a response from the employer.
