2.2.6 Section 40 (1)(a) of the Correctional Services Act compels the DCS to, as far as is practicable, provide sufficient work to keep offenders active for a normal working day, and that offenders may be compelled to do such work. Structured interviews conducted by the JICS between November 2009 and February 2010, however, revealed that only between 10% and 15% of sentenced offenders with or without sentence plans, across 74% of the country's correctional centres, participated in regular rehabilitation and work programmes. Capacity constraints, such as inadequate infrastructure and human resources, and lack of teaching materials, made the implementation of sentence plans (in those instances where inmates had them) near impossible. Correctional centre workshops and farms were underutilised and therefore underproductive. Various austerity measures have resulted in budgets for such activities being cut, and staff shortages owing to the implementation of the 2x12 hour shift system have resulted in some workshops having been closed. The DCS has reported that there has since been some improvement.
