Given what we've heard of the local authority gradient I find it impressive that a mere AIS clerk would take her objections as far as she did. We should be very very careful before blaming her for anything. If blame must be attached blame the authority for accepting the plan, not the poor clerk for merely filing it after being repeatedly belittled by the despatcher.
I can well believe that stringing up some minor player in the matter is important to protect those above from too much criticism but its a pretty shoddy way to treat the only person who seemed to object to it.
