Well, if the strike fails, the government wins. Doctors will abandon the NHS in droves, and the government will be able to use the excuse to dismantle the NHS and let the US corporates as they want to under TTIP.
If the government accepts the demands of the doctors, then the government wins. They will claim that result is massively increased costs for the NHS which are unsustainable and therefore they will be able to dismantle the NHS by letting the US corporates in as they want to under TTIP.
Either way the NHS is not going to survive as we know it.
