This is in response to The Ins and Outs of Investigations.
Just a quick note: Suggest that there be a qualification that this may not be applicable to Federal employment. Specifically, in the article, there is a reference to confidentiality.
While it is true that witness statements will only be distributed to those with a need to know, there is a difference for the aggrieved. If the aggrieved believes that the harassment happened because of Title VII reason (i.e., race, age, etc), and choose to process their issue under the Federal EEO process, they have the right to anonymity in this informal stage. The aggrieved would have to waive their right at this stage to release any information.
Thank you for the article.
