The old longer shifts vs the now shorter shifts.

[Kotlol]

If people really want to stick around for half an hour longer, then there's always the option to recall the shuttle. Two hours is also a lot of time to invest into a single shift of Space, not everyone has that kind of luxury.

The problem with recalling shuttle is the fact it has to be called in again after some time.

Anyway this ain't a suggestion but more a dicussion if people want these things back or consider it, rather then: "We got a "system" for recalling shuttles."
Since the reverse is also true if we had long shifts and say: "Well if you want a shorter shift just call shuttle."

Anyway Lord_earthfire brings up some amazing points how indeed, some departments can be done in 30 mins with their personal stuff, while others allow bigger and better things that take A LOT OF TIME! (like building a disco room)
This is stuff I didn't even think of how some departments can hit an end game and then have nothing to do... while others are making something else with the endless creativity.
