At Least In The US, there's generally two forms of tracked attrition: Regretted and Unregretted. When you say "Fuck you, I'm leaving" that's generally "regretted" -- They would have kept you, you left. When you're fired, that's generally "Unregretted" -- You have been asked to leave and your position will be filled by the next in line. Every manager wants to see their regretted attrition relatively low: It costs 2-3x the cost of the employee to re-hire that employee... but Regretted attrition being high means something is up with the (manager, org, etc) and needs to be rectified fast. Firing a whole org (or much of a whole org) tree for not coming back in en masse causes those harvard MBA types to scrunch their face and go "What's going on here, something smells stinky" and if you're lucky they see all their metrics go into the red.
