Very few nurses will earn £24k, most will earn quite a bit more.
To earn that amount, they'll have to be a new graduate, outside London with no shift allowances. So not your typical hospital nurse.
Add in shift allowances, pay progression and high cost area premiums where relevant and your typical nurse with a few years experience will probably earn £35-40k on band 5. Or more for band 6/7.
Which is quite a bit above average outside London, as it should be for a skilled graduate professional job and will allow a good standard of living, buy a family home etc, especially if they have a working partner.
Obviously the inexperienced nurse in London will struggle and the HCA payments don't fully cover the extra cost of living in the capital. Maybe there should be a scheme that gives nurses and other low paid essential workers access to subsidised secure rental accommodation near to where they work?
Having said that, the proposed 1% pay increase is an insult, especially when the 2.1% was previously mooted, and the significant vacancy rate, which I think is around 10-11% does mean that there's a problem with pay and/or conditions being insufficient for the job.
