Whether an employee has alleged harassment or reported a coworker for fraud, your company needs to handle misconduct complaints seriously. Several best practices can help you get to the bottom of an allegation quickly and avoid legal complications. For example, take every precaution to maintain confidentiality, both for the accuser and accused. Also maintain detailed notes with dates and times during every step of your investigation. To avoid bias, consider engaging an outside expert to conduct interviews. And a computer forensics specialist can help salvage and preserve electronic evidence.
