Biohazard, I agree and disagree with you in equal measure having read your comments in this thread. Burnsy makes a fair point, but overstates it. There's a fairly large number of incompetent/lazy/useless workers in the public sector, not a majority by any means but far more than you'd find in private companies. Before you go throwing the age old "ha you obviously have never worked in the public sector" I have for the past 12 years. Education department, central council and now in the NHS, prior to that I worked in a small private company.
There has always been a small number of utterly useless members of staff, generally only there because they know they'd never get paid anywhere near as much privately and somehow the management in the place completely overlooks their obvious failings, screw ups and lack of willingness to work. That simply wouldn't happen in a private company.
The other thing that happens far, far more in most local government places I've worked in is long term sickness. NHS and local councils seem powerless to ditch staff who have been off constantly for years on end, meaning the rest of the department has to take on their workload.
However the main problem is the number of managers, fortunately where I work now I have a great boss and good, strong-minded head of department. It's a first though since I started working in the public sector. Most of the management teams I've been working under or met in the past have been utterly useless, with one or two good people and the rest all there to seemingly make peoples lives a misery and increase the paperwork and decrease the efficiency of employees.
Any government will have a huge problem on their hands though - the unions. The power they have in the public sector is truely sickening and it ties the hands of so many of there "overpaid" management types who can't actually do much to improve performance when they're unable to ditch garbage staff or reward those who actually put the time and effort in.
I work in the public sector, I'm happy to take the jibes people take about this daft stereotype they have of public sector workers, but what really gets me frustrated is when people deny that there are utterly useless people raking in a damn fortune for simply turning up (or not!) and sitting on their backsides whilst their co-workers are forced to carry them - for the team.
