There are, however, guidelines to the internal investigation that are available, and the author has utilized every known facet of the investigative process to spotlight what the internal investigation is all about. Factors such as the right to privacy; whistleblowing; discrimination based on age, sex, race, national origin, religion, etc.; drug-testing and alcohol-testing; as well as prime causes of discharge or termination of employment are all relevant, and are delineated hereinafter. In most instances, these factors are evidenced by decided cases, thereby establishing precedents and background for the author's conclusions. In view of the increasing amount of litigation in this field, Freedman's treatise will be valuable to bench and bar, and as a guide will be useful to executives in corporations and organizations throughout the private and public sectors.
