We didn't go down to the individual case studies, but we certainly did ask people why they used these services. We have a chart in which we indicate the reasons that were given and what their relationship was with the length of the contracts. That's on page 38. The reasons were employee leave, pending staffing, staff shortage, workload increases. The workload increases were the ones particularly associated with the longer contracts. These are also associated with the operational and technical services.
From my point of view, whenever you have such a longer-term relationship, I think it should come through the staffing system. There's enough flexibility in the staffing system. Parliament set us a bunch of rules, so it's a parliamentary decision how the staffing system should work, and I think people should be coming through the staffing system for those longer things.
If there is a workload increase, this is a decision that is taken by managers. You should be able to plan it; you should staff accordingly. The staffing system does allow term employment, so you can hire somebody for one, two, three years. You don't have to have everybody working permanently.
