What was then the purpose of those 15 days NC after my poor reaction issuing the ultimatum?
You told your W she had 15 days to let you know her plans about the M. Then, you were asking the board what you should do next. Remember? You were told to not contact her during those 15 days. Plain & simple.
I'm done talking about the 15 days.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
