We often hear how the Federation ships have this system in place, but we rarely hear about the other shifts.
Almost always the episodes follow the shifts where the captain is active, but at that time, all of the senior officers seem to be active too. Meaning that the second and third shifts are going to be run with no senior staff
Is that normally what happens in the Navy? Or are the senior staff shared out between the 3 (or 4) shifts.
For example I'd expect the XO to oversee maybe the second shifts, not just hang around the shadow of his Captain.
