"What we've got here is failure to communicate." expands on The Risk and Expense of Terminated Participants and how victims of downsizing can perceive their layoff as unfair and retaliate:

The grudge part that Mr. Benna alludes to has to do with the plan sponsor's integrity - or lack thereof as perceived by the terminated employee….
