Nurses ask for more salary if they start prescribing drugs.
For once, I agree with their trade union (this must be a one-time opportunity). Prescribing drugs requires more training, and what's more, it comes with more responsibility and even personal liability. It is reasonable to compensate for that.
How the councils can afford that, and whether this eats away some of the potential savings that hospitals and clinics wish to achieve by delegating some work from doctors to nurses, is another matter. But what's fair is fair.
