Yes. That's the imposed contract. With the same, already ludicrously stretched resources, we're meant to pull better services out of a hat. How exactly would you suggest that we do that, if the number of calls in the first half hour of the day exceeds the capacity of the staff available on that day
Some surgeries have more resources than others. So share resources and work in partnership with other local surgeries (two of the three surgeries in my town work together, and they offer an out of hours service with the third).
Have three levels of appointment with a GP - same day, urgent (same week) and routine (whenever you can fit them in, might be in six weeks but at least they can see you).
Do the same with the nurses
Give prescriptions for longer, so people don't have to keep coming back for repeats. Have an efficient repeat prescription system eg using the NHS app. People get told they can't have a repeat without an appointment, but nobody will see them. You just can't do that. There has to be a better way like the next point.
Use e-consult or similar for easy things that just need medication or a referral, or you can decide to phone or see the person. If you get rid of the extraneous twaddle at the beginning (do you have covid etc) you can read it in 30 seconds and probably deal within 2 minutes.
I am not saying that you will meet demand. But it will at least look like you are doing something and you are not just saying no. At the moment it's often "no we can't help and we aren't going to try". And by having other options you might reduce demand anyway.
I also think a drop in session once a week for minor stuff would hoover up a lot of people. A nurse could do it and refer if they find something more serious.
