Tenure is the holding of office or land for a fixed period of time, usually granted by a government or other authority. It is a form of legal arrangement that is used to protect the rights of the holder and can be either temporary or permanent. TENURE is often used in the context of academic positions, such as professorships, where it is used to guarantee academic freedom and job security. It is also used in the context of land ownership, where it is used to protect the rights of the owner.
