Johnll, I certainly don't know the details about what you posted. I can offer you some perspective from my experience.
I meet with each of my employees often. They all know they will be asked about their mistakes since the last discussion. My concern about mistakes are about what the employee learned and how those mistakes will be avoided in the future. Not all mistakes are bad. My standard line is "if you are not making any mistakes then you are not pushing the envelope enough". My highest rated employees usually have a historical long list of mistakes. However, their mistakes are usually not repeated unless I encourage them to do it again because we gained much more from the mistake v.s. taking no action at all.
BI's BODs, including Mr. Schissler's, alleged mistakes in the past may be the best attributes of what they collectively bring to the table. If in the course of working, managing, or commanding, which they all have done, they have never made a mistake, then they really haven't done much! Sometimes the greatest learning curve is littered with mistakes and corrective action as people move up the learning curve.
BI's management is pushing the envelope of technology and management. I expect mistakes. When I hear of a mistake I also want to hear about what is being done about it so as to not repeat the action in the future unless the mistake is really a good mistake. The dialog you are having is the best solution. War is always an option but usually causes the greatest harm to both parties. Dialog is the best win-win outcome.
I wish you the best on resolution of the issues.
