Like some in this thread, I have worked in the NHS for many years, in corporate roles rather than clinical but always with the very clear understanding that our entire purpose is to enable clinicians to treat patients accurately, competently, and safely, while being recruited, paid, trained and safe (e.g. DBS checks) by us in the back office.
I've worked for organisations involved in commissioning, mental health, community provision, acute and the independent sector (thanks to privatisation by service).
I've worked in the NHS under Labour Governments and under Conservative Governments.
The two stand-out awful times of my experience were the first years of Cameron's austerity programme, when the NHS pretty much had the rug pulled out from underneath it, and the cultural war of being NHS staff working for an independent provider, we were treated so badly.
When the NHS is left to mobilise a response and get on with it, like the vaccine rollout, it's a huge success.
However, the NHS is always in the middle. Not enough GPs, patients can't get appointments, so A&E see massive increases in attendance. Social services are on their knees, so the NHS can't discharge some patients, and bed blocking has a massive onward impact to the whole service.
We are beset with our own problems, and carry the effects of problems created in other areas.
