Depending on when and where you go on your hold, and your branch for they all hold to some extent, remember you are not as well qualified as an LAC out of training. They have been trained for the job and you, on your hold, haven't.
This means if you are on a station ops desk that you are junior to the SAC there The SAC can work unsupervised and you, for a time, cannot. Takes the shine off your commission real quick. I have known one would be FC PVR after the hold. Mind you he became convinced that FC wasn't for him having watched and listened for 3 months.
