I don't underestimate the worth of good nurses, the stresses etc but £35k is a good salary. The counter to that is what are the alternate jobs that the thousands of nurses could do otherwise at the same salary, same security?it's too secure for some...
And it's not a particularly good wage for an experienced and well-educated nurse - working long hours (12+ hour days being common - and often actually planned shifts) - with no breaks and often (EDIT - almost always) a very high level of patient stress and expectation.
