A severance pay letter to an employee is a formal communication from an employer to an employee notifying them of their termination, along with the details and payment for any stipulated severance package. This document can be used to formally acknowledge the end of employment and any related financial or legal arrangements made between employee and employer. The letter should be written in a professional and respectful tone that reflects the relationship between the two parties. It should also clearly outline the specifics of the severance package to ensure that both parties have a clear understanding.
