Yes, snouts in the trough springs to mind, whoever allowed this? i believe in the 70s or 80s, a Council leader might earn 2 or 3x the average worker wage.
But of course the drive to privatise almost all council services is how they justify these salaries "we are running a multi sector business now" and getting rid of this outsourcing is where the big savings can be made, so much profit and duplication of back office functions that we the taxpayer are funding & same in NHS.
Pensions is rather difficult plus many Council staff have been Tupe'd out of their rolls with loss of pension benefits, pensions are not like for like under Tupe rules, as i can attest, FS scheme went to Defined Contribution and i lost a pension of around 15k p.a in exchange for one worth around 6k.
You cannot take away pensions that are already being claimed.
Anyway, public sector has always been the target of successive Govts to cut costs ie Austerity, who did that hit the worst?
