Had there been a blow-up, the matter would have been resolved. People would have chosen to stay or leave. Some who stayed but were dissatisfied might lobby for a change or reluctantly conclude that matters would not change, at least for a while.

Signals had been sent and quietly absorbed. Sometimes, organizations whisper.
