Why are you obsessed with the EU, what about working in Australia, New Zealand, Far East, US? The way to maximise you working opportunities ANYWHERE in the world is by having relevant transferable skills and experience in industries and professions that are needed such as medicine, teaching, engineering etc.
The flip side to opening up the market is that you will now be competing for jobs not just against your peer group in the UK, but against every person with equivalent qualifications across the whole of Europe. This will make competition for jobs much greater, reducing the chances of you getting the job you want.
A corollary to this is the basic rules of supply and demand mean that companies can reduce the pay on offer and still fill vacancies with suitable candidates. So if you are lucky enough to get a job, it will be at a lower salary.
So companies see more applicants, better chance of finding their perfect candidate, and paying less in salary at the end – see why big business loves the EU?
Working abroad is a nice thought but when it comes down to it, only a tiny fraction of the UK population ends up doing so. And at the moment, the job market in Europe is so poor – especially for young people, that there are no jobs to go to anyway.
The best way to open up a whole World of opportunity is having relevant transferable skills and experience in industries and professions that are needed.
