Thank you for trusting your question to JA today. I am a licensed attorney with over a decade of law practice and over 20 years of experience in the legal field. I’m happy to be of assistance.
The problem here is that these sorts of internal employer actions are not controlled by external procedural laws. So, while I certainly understand your concern about the contents of this report, nothing in external law will compel the employer to alter their findings or report.
You have the abilities provided by your school's due process system to appeal and submit a rebuttal, but there is no forum (at least at this point) where you can take this matter to force a change in the report. This is not a matter of "defamation of character" because the report is internal rather than being broadcast to others. This isn't a matter of lack of due process because you are receiving that. While you may disagree with the outcome of the investigation, there was an investigation where you and others were able to state their position. While you don't agree with the report, the other side won't agree with the findings...meaning neither side is really happy with it (which is practically the definition of compromise).
Agreeing to the findings is not legally agreeing to the every single line of the report. You agree generally with the result, while you can reserve disagreement with the specifics of the report. You can even ask to submit a general agreement, where you can state that you agree with the findings, while reserving disagreement with some of the items contained in the report. If the school is willing to accept this, then you are fine.
If you have any further questions, please let me know. I invite follow up questions, so use REPLY for those.
