Hmmm..
They've been telling us all along that they're the experts on what's going on in the NHS and assuring us their intended strike action wouldn't be putting lives at risk. Now suddenly they're presenting this welcome change of heart as though it's been brought about by some new set of circumstances previously unknown.
Frankly I'd have a lot more respect for them if they just admitted they got it wrong, now accept that their strike plans would have put patient lives at risk so have abandoned that course of action for good. There's no real sin in accepting an error of judgement and proving, for any doubters, that they do put patient lives at the top of their list of priorities.
