And really, the whole thing of the Trek series only focusing on the senior staff is silly, since it means the senior officers are the only ones who do anything. But in the real world, the higher you are in the pecking order, the less work you do. Military or civilian work environments, it's the lower peons who do all the work while the managers/higher ranking officials are usually sitting back watching others do the work instead. And bitching at them to work harder. But in Starfleet, apparently the higher your rank, the more work you're expected to do.
