My conclusion is that this is not very well managed.
Is it encouraged or discouraged? I think many managers have just put their hands up and are letting it happen, which I think is not correct. In one sense, these are public servants who have had the training on what the public service is about. You continue with that gain: they know what public service is about and they're moving.
If somebody has been in a job for three or four years, it's probably a good thing for them to move. The ones I worry about are those moving after a year or a year and a half. There's just too much of that. In some cases, movement is a positive thing, for the person and the career. When you have a lot of movement—particularly PEs and ESs are the worst ones—you have a lack of continuity. You have to reinvest in knowledge transfer.
Our systems in government, in terms of data and data holdings and knowledge management, are not as good as they should be. There really is a problem with continuity. It's a more difficult environment to manage in, and a lot of it is not necessary.
