@Arella Mae,
Arella Mae, listening to that tape only reinforced what you knew had been said at that meeting. It's not as though you had no memory of the meeting without the tape--all the tape did was convince you you were right in what you remembered.
It is not a lie, at all, for you to say that you recall what was said at the meeting as being different than what is in the minutes.
It would be a lie to say you misunderstood what was said, which is why you should not say that.
You seem to feel you are being pushed into lying, but if you just say that you remember what was said, and it differs from the minutes, and that you have confidence in your memory, that isn't a lie in any manner or shape or form. You do have confidence in your memory--because you have your tape to back you up, even if they don't know that.
I understand what you are saying, but you really don't have to refuse to sign the minutes if they include your statement with your version of what you heard, and what you know to be true.
Since you have a lawyer now, it might be easier for you to write your statement, including what you heard Dave say, have it appended to the minutes, then sign
below that, so it is clear that you are not just signing the minutes as they were presented to you--your signature will include your "correction" and it will be below both the minutes and your statement . That way, you wouldn't just be signing the minutes. I think that would be easier on you. Then, I'd let the lawyer do battle with them. Give yourself a rest.
