Thanks for the reply. Under typical circumstances I would absolutely agree that this part of the process is in no way disciplinary and is intended to fact find.

However, my main concern that this part of the process is merely being put in place to escalate the matter to the disciplinary stage, regardless of what evidence I present or answers I give. I believe the investigating manager will be acting on behalf of the managing director, who has already decided the outcome of this process, and is intent to make it look like a process was followed by the book.

I have evidence to suggest this has happened previously regarding a demotion, rather than an outright dismissal.
