The EEO complaint investigator takes testimony from relevant persons in affidavit form under penalty of perjury. Your appointed representative may help draft the language for your affidavit, but only you can sign it. Your statement must be true and correct.
The EEO complaint investigator asks you to provide evidence about the remedies to which you believe you are entitled. You must provide relevant evidence about the remedies, including medical reports and other personal documents.
There are penalties for making false statements. Section 1001, Title 18 of the United States Code states that whoever, in any matter within the jurisdiction of the executive branch of the United States government, which includes the Postal Service, knowingly and willfully does the following:
…falsifies, conceals, or covers up by any trick, scheme, or device a material fact; makes any materially false, fictitious, or fraudulent statement or representation; or makes or uses any false writing or document knowing the same to contain any materially false, fictitious, or fraudulent statement or entry; shall be fined under this title or imprisoned not more than 5 years or both.
Providing information that an EEO complaint investigator requests is mandatory both for you and any Postal Service employee witnesses. If you do not provide the information the EEO complaint investigator requests, your complaint may be dismissed.
