It seems that you are looking at this question from a legal point of view...?
BUT....Some reasonable terms to a contract can be implied.
I was looking at it from the point of view of what we can REASONABLY expect from the NHS - considering how well we fund it.
The NHS is definitely nowadays feeling short of money but that is partly because it wastes so much of the money we do give it.
At the moment some (1995 scheme) NHS nurses can still retire at age 55 on a full pension with a net present value of their expected pensions over the following 30 years of ..... npv = well over £1million.
They can then continue to receive the FULL pension AS WELL AS continuing on in their job (so long as they make sure the job is converted onto a non-NHS contract).
So a senior nurse might receive £32,000 pension + £60,000 salary = £92,000 per year.
Doctors' pay and pensions are far superior even to that.
Very many GPs are reducing their hours / retiring early
BECAUSE THEY CAN AFFORD TO DO SO.
We taxpayers / patients / prospective patients are paying the NHS enough money to have their staff on great working conditions
- multiple weeks holidays beyond normal expectations - multiple weeks off and funding for training, final salary pensions INDEX LINKED for future inflation.
Obviously all of the above is nice for NHS staff - ut is unaffordable for the country.
It is particularly offensive to patients who are private sector workers who are hard working taxpayers - (some of them at an ACTUAL 'COAL FACE') who over the years have had much less security of employment than public sector workers like NHS Staff (at the much talked about 'NHS coal face'), and who can only dream of final salary pensions - long ago abolished for most private sector 'hard working families'.
Only now belatedly ...is the NHS realising that they MUST NOT waste money on things like triple paid agency doctors and nurses etc.
If someone in the NHS pension scheme became unwell they could retire on a good income for life -unlike the lady in our example.
No surprise then that the hypothetical sick lady on £70 per week sickness benefit to live on
in the example was not happy to be asked for a £25 fee - even if it was to go into 'practice' funds.
(but probably not even ringfenced as additional funding - and therefore forming part of distributable profits amongst the GP partners)
GPs in England are the second best paid GPs in the entire world apparently.
USA is apparently the top payer, but there the GPs have to pay megabucks for their own medical training, so taking that into account UK GPs are possibly the best paid in the world.
Some GPs are earning literally many hundreds of thousands of pounds per year from the NHS. This is well documented in the media.
GP Medical Practice funding is already provided to the practice by the NHS but If the GPs are so worried about funding the running of their practice why don't they take a salary cut?
The £25 charge is rather obscene.
