An operator is a professional designation used in various industries, including broadcasting (in television and radio), computing, power generation and transmission, customer service, physics, and construction. Operators are day-to-day end users of systems, that may or may not be mission-critical, but are typically managed and maintained by technicians or engineers. They might also work on a 24-hour rotating shift schedule.
