The TERM 'Period of Office' refers to the length of time a person holds a particular job or position. It is often referred to as a 'TERM' (4 letters) or 'TENURE' (6 letters). This period of time can vary depending on the job or position, and is usually determined by the employer. It is important to note that the period of office does not necessarily refer to the amount of time a person has been in the job, but rather the length of time they are expected to remain in the job.
