Which of the following is a prohibited work assignment for prisoners?

The prohibition of work assignments for prisoners that require access to drugs is based on safety and security concerns within correctional facilities. Such positions can pose significant risks not only to the inmates assigned to the jobs but also to the overall environment of the facility. Allowing prisoners to handle or be in close proximity to controlled substances increases the potential for drug misuse, trafficking, or other illegal activities.

In contrast, tasks like office cleaning, cooking, and library organization are typically seen as less risky. These assignments can help inmates develop skills and contribute positively to the institution, provided they are managed under strict supervision and guidelines. However, any job that could potentially facilitate drug access or compromise safety is generally deemed unacceptable and thus prohibited.
