I'm not asking any question, I'm disputing the central claim in this strike.
It's almost impossible for a nurses pay to have fallen over the last decade in real terms or any other terms.
Take a band 5 new nurse starting in 2015, by 2022 their pay would have increased by 34%, well above inflation. A new starter in 2010 that didn't ever get to band 6 in those 12 years would have had a pay packet 50% higher than the day they started.
Picking average pay is misleading as it' can be skewed by newer starters, so you get unions screaming for more trainee nurses followed by unions screaming that average pay has fallen because they got all the new trainee nurses.
If the argument is pay stagnation as it seems to be then it's reasonable to look at how many nurses pay is actually 19%, 10% or even 1% lower in real terms than it was at the time chosen.
If the argument is starting salaries haven't risen then that's slightly different but as 26000 people accepted the starting salary in the last couple of years they can't have thought it was so measly.
If the argument is nurses are generally underpaid then again that's slightly different but the NHS wage bill is ~60bn (how has this risen above inflation if pay has fallen?) with 1.2m employees, that's funding for about 50,000 each on average.
