The size of your Workshops will determine how many prisoners can work from the room. They will be working in the workshop during work regime, if enough jobs are assigned there in the Prison Labour view of the Logistics menu. Prisoners must complete the Workshop Safety Induction Program before they may work in the Workshop, plus the Carpentry Apprenticeship Program to be able to make beds. Workshops can be built after Prison Labour has been researched via the Bureaucracy system. If there is one, wood may be sold manually, or turned into Superior Beds, which again will be sold. Logs (that can be bought or produced in the Forestry) are dropped off here and are turned into Wood (using a Workshop Saw), which will be sold automatically as long as there is no Carpenter Table. First, the sheet metal is cut into smaller pieces using a Workshop Saw and is then pressed into License Plates using the Workshop Press. Sheet Metal is dropped off here and is turned into License Plates which are sold for a profit at midnight. Prisoners can work in the workshop making License Plates and Superior Beds to increase the prison's income. After researching Prison Labour, prisoners can be assigned to work in this room.
This room must be researched before it can be used.
