If you exclude layoffs and incentivized retirement, it seemed to be that a greater percentage of individual contributors left as compared to managers. Lots of managers stuck around for 12+ months, and it seemed like the percentage of managers of managers (e.g. directors, VPs) who stuck around was even greater. Almost the entire C-suite stayed for years after the acquision.
Was there any financial or other incentives given to managers to stay? As an individual contributor, the morale was just terrible. I just couldn't understand why the managers and other people in leadership positions stuck around.
