In colloquial terms, it's the document that makes a firing official. The cause for it may be known or unknown, and it always relies on the hands of the head of the department to decide on termination. Often, it is bad news for both the parties involved and the most polite formal way of giving the notice of termination is through a letter. Employee Termination Letters are generally one-sided, in that there is no negotiation and the employer is merely alerting the former employee to need-to-know exit information.
If the terms of the firing are more mutual and amicable, consider using the separation agreement instead.
