I know this is a bit late, but I have worked in the Public Sector for two and a half years here and on the whole it has been quite good The benefits of it are:
1. Excellent pay, especially when you get up to higher positions--much better than the voluntary sector
2. Great benefits--loads of A/L and TOIL (I get a total of 37 days/ year plus time off for studying my masters) Also, they offer relocation packages (not bril, but helpful if you want to move) Loans for buying cars, bikes, season tickets, etc
3. They really value Americans. I think this is for many reasons--we tend to be better trained with more "practical" experience than our UK counterparts and also they are all trying to work more efficiently. Americans (on the whole) see through the bureaucracy a bit better and can be very helpful in reform
4. there is a major staff shortage, especially in upper management, so the chances of getting a job are high
There are some definate negatives:
1. Community development here is working with voluntary groups and it is generally very poor. Everyone gives lip service to working with communities, but don't generally do a very good job.
2. Local government officers can be very difficult to change (not all, but a lot). They see themselves as the experts and no one else better challenge that (I work to develop interagency partnerships and it is a struggle to get people to change).
3. The bureaucracy is unbelievable and worshiped like a god.
On the whole, it is good and there are loads of resources to get jobs in the public sector (Guardian on a Wednesday
www.jobsgopublic.co.uk --both advertise jobs across the country)
I currently have a joint appointment with the NHS and the Local Authority and I know that both orgs have MAJOR problems finding qualified people--which is the same throughout the country.
Hope that is helpful!!
