Independent workplace investigations are appropriate when Human Resources is too close to a situation, does not have the resources to conduct an investigation, or  an in-house investigation will not have the credibility needed given the risks to the organization. An outsider can take a fresh look at the dispute or the complaint, unhampered by preexisting relationships or a stake in the outcome.
Open the Blinds Investigations offers investigative services to employers regardless of locale, and brings years of experience with employment law and an interest in the culture of workplaces. Contact me for further information.
