Private investigator occupational outlook handbook, 2010-11 Edition
Many detectives and investigators spend time away from their offices conducting interviews or doing surveillance, but some work in the office most of the day conducting computer searches and making phone calls. When an investigator is working on a case, the environment might range from plush boardrooms to seedy bars. Store and hotel detectives work in the businesses that they protect.
Investigators generally work alone, but they sometimes work with others, especially during surveillance or when they follow a subject. Some of the work involves confrontation, so the job can be stressful and dangerous. Some situations, such as certain bodyguard assignments for corporate or celebrity clients, call for the investigator to be armed. In most cases, however, a weapon is not necessary, because the purpose of the work is gathering information and not law enforcement or criminal apprehension. Owners of investigative agencies have the added stress of having to deal with demanding and sometimes distraught clients. Although considered a dangerous occupation, private detectives and investigators have a relatively low incidence of nonfatal work-related injuries.
Private detectives and investigators often work irregular hours because of the need to conduct surveillance and contact people who are not available during normal working hours. Early morning, evening, weekend, and holiday work is common.
