Letter of resignation Such a letter will often take legal effect to terminate an appointment or employment, as notice under the relevant terms of the position; many appointments and contractual employments are terminable by unilateral notice, or advance notice of a specified period of time, with or without further conditions. Even where an oral notice would be effective, the effective date or time of termination may be directly or indirectly fixed on delivery of a written letter or email, for the sake of clarity and record. In response, different arrangements may be made or agreed, such as an earlier effective date, or improved terms and conditions of appointment upon withdrawal of the letter.
