Very few people, by the look of it. This report on Children & Young People Now today gives the unsurprising news that nearly half of all directors of children's services in England have either left the post or moved authority in the last two years. Unfortunately, the report doesn't go into any more detail, so we don't know how many have left completely, or how many of those simply left because they had reached retirement age (although the report goes on to quote someone from the Improvement and Development Agency for local government, who says that many DCSs are nearing the end of their careers). Nevertheless, such a high rate of turnover must surely be a cause for concern.
The news of course follows in the wake of the Sharon Shoesmith decision (which I discussed with Natasha in our LoreCast last week), and the media vilification of social services generally in the last couple of years.
