I have said this before--I hope you got the book From Emotions to Advocacy. I think that the way you document going forward is crucial. Pete Wright really knows his stuff, and I strongly believe that his approach is more likely to get what you want in the short term, and in the long term if you go to due process much more likely to result in a favorable decision.

This link has good articles but I think it is worthwhile to get the book.
