FWIW OP, until I went on mat leave a few weeks ago I hadn't been on mumsnet for 2 years because I was too busy, er 'working'. I work in the voluntary sector in a publicly-funded role. Because the local authority has contracted out my job, I have no pension or contractual maternity pay. If / when the funding for my job is cut next March, I will be very cheap to get rid of as only on a yearly contract. So you see I save the taxpayer a fortune. I'm sure you approve.
Meanwhile my DH works as a cover supervisor in a school. Since employing him a colleague at precious little above the minimum wage instead of paying for qualified supply teachers to cover lessons, his school is saving £90k per year. At the moment we are so skint he has had to opt out of his contributory pension.
Unfortunately DH and I are 'working' so hard saving the taxpayer a small fortune on our salaries and pensions, ends don't quite meet so we rely on tax credits to top up our income and pay our childcare. I suppose this makes us scroungers too??? 
So I'm afraid I'm with the other posters OP. Fuck off. I hope your bins don't get collected and you get rats. And that your kids don't get their GCSEs because they were taught 40 to a class with no textbooks. I'd like to hope you're left without an ambulance one day but can't, because like many of us who work in the cushy kind of job you take if you want to help others, I'm a nice person. So without any extra insults, just go fuck yourself.
