There are very few of what we would call separations.... The voluntary departures number in 2007-08 was 2,340 people. That's a pretty small number, and if you look at it, there were concentrations in the ES and the IS group. These are fairly young: they got into public service and decided public service wasn't for them and they left. These are really small numbers.
The big movement we're seeing is inside the system: people going from one department to another. They may not like their boss; they may not be interested in the work. Most often they feel they have greater potential for development in another place, or promotion.
