I knew of a certian PO that had often stated, "The CO is here for a few weeks and then he's gone." In other words, tell him what he wants to hear and he's gone. This would make for the same local needs talk to be given over and over with the same problems that the CO addressed. I was in that congregation for 5 years and it was all one big rerun.
Also whatever the elders say about u to the CO is taken as gospel. A friend of mine was an elder until the other brothers ganged up on him. They waited for a technacility and when the CO came around he was removed.
