It's not even as good as the Mafia.
The Mafia has very clear cut rules that apply to all its members. You break the rules, you suffer the consequences. There are no exceptions.
PAL management is more like the Philippine government. The leadership is corrupt. Those being led are either oblivious to this fact or are resigned to accept the status quo. There are good people all over the organization. If you do your job well and keep your mouth shut, you keep your job. Squawk about the corruption loud enough and you're toast.
Violations of policy can result in harsh sanctions. But if you are well-connected nothing will happen to you and everybody else will be told not to do what you did.
One idiot couldn't get his APU started at an outlying station with no ground support equipment but managed to deplane his passengers, unload the cargo compartments, load them up again, then board the outbound passengers without having to shut down both engines. He still works there.
But then he is a classmate of the fellow who wrote the subsequent notice to pilots prohibiting everybody else from doing the same thing. But everybody else already knew that!
Go figure.
