While board meetings normally are relatively sparse, most of board work happens between these meetings (where you effectively perform any voting rituals required to formally approve the decisions the board members made beforehand) and it is very common practice for executives to continuously keep board in the loop - arguably doing this well is one of the primary duties of a CEO.

Yeah it’s absolutely weird. The board is supposed to be the top governing body - they need sight of future plans. And if something changes in middle of quarter then at a minimum a mail or phone call as a heads up.

They probably didn’t expect quite that big of a reaction sure but hard to believe they didn’t know at all that it would be important.
