    Corporate investigators (私家偵探 )conduct internal and external investigations for companies. In internal investigations, they may investigate workplace drug use, ensure expense accounts are not being misused, or determine if employees are stealing assets, goods or information.

Investigators could spend months posing as company employees to uncover wrongdoing.


    Financial investigators may be hired to develop confidential financial files of individuals or companies that are potential parties to large financial transactions.

Store detectives also regularly inspect stock areas, locker rooms and lounges, and sometimes assist with store openings and closings.
