In the midsection of the cabin, there were folding bunks for off-duty crew on long missions.

So on the ship's last night in Federation space, Saavik found herself at a party with the off-duty crew instead of studying.

The entire off-duty crew assembled again to watch.

The dormant engineering section had been transformed into a storm of activity as off-duty crew tumbled into the room, racing to their reactivated posts.

"What sort of facilities does it have for off-duty crew?"

A task which the whole off-duty crew undertook and which, to me, seemed a rather pointless exercise.

With most of the off-duty crew and virtually all the civilians up at the party, SDF-1's passageways were empty, giving the ship a haunted feel.

Her off-duty crew were in their hammocks.

This isn't your job or that of the crews off-duty and at the other stations.
