Ive already mentioned the waste of paying off the failed chief exec £270K.
.
The chief exec wasn't a failure: it's worse than that, she was replaced because she had been appointed by the previous administration and Labour wanted someone more in tune with what it was doing. That's not an anti-Labour point: the Greens did exactly the same thing, as did the Tories before them.
In central government, civil servants aren't sacked when there's a change of administration and I see no reason to do it in local government. In the past decade, the council must have spent close to a million quid getting rid of officers, money that could have been better spent.
