Admin is a very broad and general term. Different people do it in different ways, but the common definition is someone who manages systems and processes, often through computer software, to provide support to others. These are usually done remotely with fewer than 30 hours per week. They may manage email or calendars, provide help desk support, manage databases (such as payroll), track performance metrics, keep records of expenses and much more. The biggest distinction between the many types of admin employees is the age range they typically work in: Some do it part-time while others are professionals who work full-time on their job.
