Right now in the federal public service there are people who are in a position where they can retire, but they are staying and taking on a mentoring role. It's a very powerful tool that the government should be using.
On how to get them to stay and mentor, I've had people in senior positions say they're only working for peanuts. But they like their jobs, they like what they do, and they like the values in the public service so much that they stay to pass it on.
We need to identify ways, no matter what they are, to make sure those people stay around.
