Promotion Letter

 A promotion letter is a formal document that informs an employee that they have been promoted to a higher position within a company. It's a way for the employer to recognize the employee's hard work and reward them with a promotion. 

A promotion letter typically includes the following information:

The employee's new job title
The employee's new responsibilities and expectations
The employee's new reporting manager
The employee's new compensation and benefits, including bonuses, raises, and other perks
The employee's new start date
A congratulations to the employee
An invitation for the employee to clarify any questions 

Promotion letters are usually a follow-up to conversations that have already taken place between the employee and their manager. The letter confirms the details that have already been discussed, rather than presenting new information.
