I reckon it would cause more havoc if we went out of CC for a few months and then use it again if the new RP's are not acceptable.
It also shows them how much our goodwill would benefit them.
Imagine; everything would run on time again, no cancelled flights, you can hear a pin drop in crew control...
If you are in constant CC, you are losing the benefit of the bad, if you don't show the good every once in a while.
