I think the, this is quite well illustrated by the figures on employees, where the numbers employed fell by getting on for ten percent, though our spending on employees remained about the same, partly as a result of pay increases, partly also, as a result of changes in the profile of grades of the staff at the Council, and a movement towards better staff, better paid, and then finally the saving we make each year as turnover of staff occurs, and we don't have to pay salaries during the handover period from one person to another, that saving that has reduced because the turnover of staff has reduced.
