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.
This sort of internal investigation isn't a "due process" situation, like a court appearance is. As such, you aren't legally entitled to representation. You can certainly hire an attorney and refuse to cooperate with the investigation unless your attorney is present, but because it's not a court they can just do the investigation without your input and reach their own decision without the attorney you hire ever having a forum to speak before.
So really, there isn't much value here in trying to obtain an attorney before the hearing, because unless they agree to allow you to bring one (exceedingly unlikely), the hearing is going to either happen with you alone or without you.
The time to speak with an attorney would be after the resolution of this situation if it is not favorable, so as to figure out if you have a breach of contract claim.
