It's a good question. Can I just make a couple of comments?
The growth in the public service is not something the Public Service Commission does; that is a government decision. When estimates are reviewed, that's the obvious place to ask questions about the growth and increases in budget. Do they mean increases in people? Are you going to hire people or are you going to contract? Those are really government and then parliamentary decisions. We at the commission are making the observation on how the system is working and how the staffing system is working.
We have a preoccupation about the staffing system, and I agree that if we spend a lot of time looking at the numbers.... And there is not “one fix for everything”. We looked at different occupational groups, at different settings, and at the dynamic of what was going on in those occupational groups. One general statement doesn't apply to everything.
It is obvious to me that this whole system has to be better managed. I think there is an obligation on the employer, the new CHRO, to deal with this in terms of how it is managed.
We now have a system in which, for some occupational groups—look at one of the charts we have on the table, for the ESs—they've all moved within a year; none of them is in the same job. Some of this could be because the job has been re-labelled: it could be that they're doing the same job but it has a different title—and that is the only way we can judge it.
That's a very hard system to manage. It's very hard for providing service and for providing any kind of continuity. But people are staying in the public service. We have people leaving, but not in great numbers; they're staying in the public service.
So I think it's a big management issue. When members of Parliament review estimates and have managers in front of them, asking them how they manage this would be helpful. We keep on about the planning, but planning means not just having a plan; it means looking at your workforce, at the different components of your workforce, and having a strategy for how you are going to replace and renew those different components.
It is also very important for public service managers to work at really actively engaging their employees and having the conversations with their employees because they stay in the public service; they just go and work for another department.
It's a system that has resulted in some sectors and some places having too much movement—what I call classification creep. You see the classification levels going up, which doesn't seem appropriate. In some places, for some groups, I think we've gone through the big retirement, and you see others for which it's going to come. The AS group, you can see, is older; it's going to come. ESs and PEs have done it, and they're now newer.
