Hi if your working with council tax + HB I'm assuming your in the finance department of your local council...
As much as I hate my own local council I did used to work for them,for me it was depressing because it seemed nothing more than lazy people in their own 'clique' pushing paper around trying to look important..
I found the whole thing irritating because I knew I was paying taxes for these people to do this.
However if you don't feel the same way as me then you would be hard pressed to find a more secure career with pension etc...
I left on good terms after a year I now work for microsoft, but I didn't do any courses to get here,just started at the bottom...
I enjoy my job now but it is a risky decision to leave such a secure job, make sure you find something you know you'll stick at...otherwise you'll be no better off than you are now...
