Fact Check or Brass Neck?

Channel 4 News FactCheck - a blog which supposedly 'goes behind the spin to dig out the truth and separate political fact from fiction' - takes issue with UNISON's widely reported research about the scandal of nearly four people chasing every vacant job in the UK and err..... confirms that it is accurate! Likewise the union's claim that a phenomenal 500,000 public sector jobs have been lost since May 2010 is confirmed as err..... factual. Selective facts maybe, but when the point of a campaign is to highlight the downside of austerity, why on earth would the union spin on behalf of the Government?
