I've picked English speaking countries as it's easier to pass the exams required to practice abroad than learn a new language in my opinion. Once UK salaries reach that of other countries we might get out of the recruitment crisis. However currently we are cutting pay and down banding roles which doesn't make people want to stay in the NHS or indeed the UK, we only stay because of family.

What the unions are calling for is considerably less than these figures, maybe what they should be calling for is a review of agenda for change with international bench marking of salaries.
