A relief for cause report is very serious. These are rare events and therefore they receive a lot of attention from promotion boards and quality management boards.
I would encourage you to read AR 623-3 and DA PAM 62-3 as they pertain to appeals and then I would encourage you to submit your appeal if you meet the requirements stated in the above references. Keep in mind that if your appeal is your way of telling your side of the story and may be of assistance in preventing the quality management boards from removing you from service should your appeal be granted in whole or in part.
