@NJ So? The jobs are offered here as well. If the employer cannot find anyone here to do the job, what do you want them to do? Work short-handed? Press -gang the workshy?
Look at some of the jobs being advertised. Some mentioned, at least as far as the short description in the article goes, sound relatively high-skilled. So, at least for those particular jobs, the prospective employers will either get a raft of local candidates assuming the job is offering a competitive salary and conditions, or they won't, because there are insufficiently qualified local candidates, or the local candidates are uninterested for a whole host of reasons.So you tell me - what's an employer to do in those circumstances?
As an employer myself, I will hire whoever offers me the best bang for my buck, be it a home grown candidate or one from abroad if necessary. And you know what, a home grown candidate is almost always going to fulfill the role better, because of secondary considerations, like language skills, common cultural referents etc.
Just because the jobs are advertised europe wide does not automatically mean that a non-briton will get the job.
If you stopped greedy employers trying to enhance their own profit margins and shortchange the minimum and living wage for the low wage low skill jobs by hiring foreign migrants, that might go a long way towards reducing the need for such employees.
