A Last Day of Employment Letter (also known as a Termination Letter or Separation Letter) is an official business document that serves to inform an employee that their employment has been terminated by their employer. This letter informs the employee of the date when the termination will take effect, and provides official notice of the reasons for the termination. The letter also confirms the end date of any benefits and rights related to the employment. In some cases, this letter may also contain details of any severance pay or other compensation due to the employee. It is important that this letter is written in a factual and unbiased manner, using business language and tone.
