GPs going on strike - what on earth??

GPs going on strike seems bizarre. I thought they recently had a massive pay hike, or was that the press lying to us. In 2000 Gps were earning £60k and the press reported a pay hike to over £200k. At half pay for a pension that's an increase from £30k to £100k, regardless of which index is used for inflation that's a massive increase. Anyone know the truth about this? Or are GPs being incredibly greedy. Seems the way of the world...
