Tenure of Office is a TERM used to describe the length of time a person holds a particular job or office. It is usually determined by the terms of the contract or agreement between the employer and employee. The TERM can also refer to the period of time during which a person is allowed to remain in a certain position, such as a government official or a professor at a university. In some cases, tenure of office may be indefinite, meaning that the person can remain in the position for as long as they wish.
