It would go up and down somewhat, but it would be fairly typical over the last several years. If anything, I think we would anticipate it growing marginally as the demographic bulge in the public service works its way through.
Frankly, this is one of the concerns that all of us have as managers in the public service: that we balance that with the need to retain and recruit fresh blood into the institution. But we take that into account, and something that we've been doing much better at in recent times, and that now, as we head into this fiscal climate, we'll have to get better and better at, is forecasting what the attrition rate is so that we can plan appropriately at the other end. But it has been relatively stable, as a trend.
