There's a catch 22 in there somewhere, the fewer staff they can attract, the longer the working hours will be for the rest, but there are some mixed messages when it comes to attracting staff, though.
In the case of nurses, the BBC recently reported that there are 200,000 applicants for just 20,000 vacancies, so there's not much sign of nurses being overworked and underpaid there.
On the other hand, they're reportedly having to pay bribes to get GPs to go and work in Essex, but I don't know whether that's a reflection on Essex in general, or the standard of Essex surgeries in particular. Perhaps there's a catch 22 there as well, if Essex can't attract the best doctors, that will be reflected in the performance of the surgeries.
I recall when we used to grumble about morale/pay/conditions etc. at work, the management response was always the same: our staff turnover rates are no worse than anyone elses. The turnover rates for both doctors and nurses are about 1% per month, which is well below the average of 15% per year, and follows the trend of lower than average turnover rates for the public sector in general.
