I think we're getting there.
I was not an employee but just a volunteer and President. Our bylaws state that once a resignation has been presented, the party cannot change his mind. This is no problem for me since my goal is to have the evil doer removed along with those who ignored the evidence of wrong doing.
Thus, if I understand you correctly, another member of the board must call that meeting and seek a new vote after stating the violations and indicating that if members agree that the violations have occured, must vote to remove. Is that correct?
