Thanks for the question. It is a very good question.
We are, as I mentioned, facing accelerated retirement now, 3.3% a year on average in recent years. So we do need to concentrate on how we are retaining the knowledge. Part of how we're trying to do it is anticipating retirements before they come up and ensuring that the knowledge and skills that those people have are explicitly being transferred through coaching or mentoring of new staff coming along.
Part of it is in identifying when people are going to be retiring. They do have flexibility, and sometimes people don't want to say when they're going to retire. That can be a bit of an issue for us.
I think trying to transfer skills person-to-person through coaching and mentoring, as well as ensuring that we have the kind of information systems that capture what we need from their corporate memories, are also important.
