It is indicated that some of these actions are in fact good and right, truly purposeful and just. However, their implementation my be justified by the normal risk that any business activity bears. The central problem of the entrepreneur to find a level of security that is optimal under the given circumstances, while remaining morally balanced in the sense that the employee is not treated as a potential or actual thief who cannot be trusted. The task is very difficult, particularly for an entrepreneur who takes business ethics seriously. Observing ethical standards may not be an excuse for exposing the business to a thief or fraudster.
