Many different problems can arise in a company that lead an employer to recognize the need for an investigation, and not every investigation necessarily fits the pop culture profile of small room interrogations, witnesses under harsh lights and glum-faced detective work! A properly conducted workplace investigation – one that is prompt, thorough and objective – can help defend a company should a lawsuit be filed later. Typical reasons include substance abuse, discrimination complaints, threats against others, harassment complaints and workplace theft. Employers and employment law attorneys recognize that an in-house investigation may not be unbiased, simply because managers may not have the skills to conduct an investigation and have a natural loyalty to their employer. In a court of law, the in-house investigation conducted by a manager or by human resources may be determined to be too one-sided and only for the purpose of exonerating the company rather than determining if the employee was treated fairly.
