Gary, you've got it exactly. The Cosa Nostra in general worked similar to a corporate or military structure (actually, kind of both), and in both of those structures the chain of command is THE method for resolving differences. Beyond that you could appeal to a higher-ranking boss, but not until you go to your immediate supervisor/manager first. Very rarely did someone go rogue and challenge their senior member since that was a one-way ticket to the mortuary.
