Operators also work in other settings. Communication-center operators handle airport authority communication systems. For example, they use the public address system to page passengers or visitors. They also monitor electronic equipment alarms. Service advisors monitor conversations between operators and customers to observe the operator's behavior, technical accuracy, and adherence to company policies.
Many telephone operators are also receptionists.
The hours of PBX or switchboard operators generally are the same as those of other clerical workers in the firm. In some organizations, they work 40 hours a week during regular business hours. Operators in hotels, hospitals, and other places where telephone service is needed on a 24-hour basis, work shifts, even on holidays and weekends. They also may work day, evening, or night shifts, which include weekends and holidays. Some operators work split shifts that is, they are on duty during the peak calling periods in the late morning and early evening and have time off in between.
