This book condenses a complex and important subject -- conducting investigations regarding allegations of workplace misconduct -- into a succinct and straightforward manual for managers and investigators in the public and nonprofit sectors. It explains when and how to conduct investigations, interview witnesses, assess the case and write the investigative report, and warns against the pitfalls that investigators and agencies should avoid when confronted with workplace misconduct. The authors also discuss a variety of special investigative challenges, including new case law on confidentiality, conducting investigations in a unionized environment, special rules for public safety officers, and dealing with implicit bias in investigations. This Sixth Edition contains significant updates and revisions from the prior edition.
