A sense of relief may be a coping mechanism. I've heard laid-off colleagues inform me they felt relief in the immediate aftermath; granted, the lay-offs were pre-announced before they communicated who would be "impacted", and it was at a high-pressure environment; but the human mind sometimes reacts in unexpected ways to loss outside of one's control. Rationalization is a mechanism for ego defense.
