I am a nurse, have worked at private and public hospitals both in the US and UK. Like has been said by many others, both have their plusses and minuses. I have seen some horrific staffing levels in both places. In my experience, it has been far unsafer in the US. We had a 24 bed Intensive care unit staffed with 8 nurses at best over the winter period, weren't allowed to use agency nurses, just left to get on with it. They were, for the most part, ventilator dependent, staffing should have been 2 nurses to 1 patient, but we had 3 each most days. Many unfavorable outcomes happened that were directly related to staffing. They had stress debriefing sessions for the staff, things were that bad. But no extra nurses, no onsite doctor, no auxillaries.
Here, while not perfect, I have only had 2 patients twice in 5.5 years, have the ability to call in more staff, agency or bank, we are able to close the unit to admissions if staffing is unsafe, have great doctors (for the most part) in the unit/hospital at all times, are able to take time off to care for sick kids, or be sick ourselves without being penalized.
I know it isn't this way throughout the UK, but it is here. I feel for those of you that have to work in substandard conditions. Been there, feels like hell. I hope it improves, or you can find a more supportive place to work. I wouldn't work under those conditions anymore.
