It is not only the responsibility of the Investigator to gather information. You must also collect evidence. This guide will help you find documents that may help your case. It will also show you some important things to remember.
The other party may have documents that you believe will help support your case. These types of documents must show that:
a) under similar circumstances you were treated differently when compared to others.
b) this treatment was different because of your membership in the protected class(es) stated in your complaint. If you know of any documents (like employee performance reports) that the other party has that may help your case, tell the Investigator. The Investigator will be able to get copies of documents from the her party. You are not allowed to directly request documents from the other party at this point.
It is your responsibility to tell the Investigator about any documents or files that may help your case.
