I always found it strange for not only the XO to be on the bridge at the same time as the CO, but the entire senior staff were always on the same shift.
Not only that but in voyager you had ensign kim who was at ops during the day shift with the rest of the senior staff but then was included on a secondary night shift since most starfleet ships seemed to use a three shift rotation he was on for two shift out of three.
