If they wouldn't react to 8+ hours of work, this mod would be a money printing machine. Not exactly what one would like, no?

You can deal with that through the policy tab.

If they do cause trouble for not liking being slave labour, send them to soliary for 24hours for any infraction. They come out like docile farm animals and they are less likely to do anything rash for longer.

I see what you are getting at, and perhaps it would be nice if the prisoners were a little more docile in IA. However, i see it in a thematic sense. If you imagine that most of the prisoners are either rebel scum (Oh dear i've gone local) Or other malcontents. Well, how many rebels and, say, crime lords and such can you see that are going to just sit there and get used to do the Empires bidding all the time? Look at leia when she was locked up in the death star, she still gave them some cheek. Which pretty much seems to be the rebel way. As for criminals of the SW universe, most like to instill a little chaos into things. Just look at Han.
