Don't be surprised if a farmer who voted in favour of Brexit asked for Romanians to come and pick his fruit on the basis of a premise that isn't quite genuine.
What they probably means is that Romanians/et al are absolutely shit hot at picking fruit and can do it 2x 3x 4x etc. more than a local resident and that it makes more financial sense therefore to have those foreigners flown in to do the job than to train up local residents to do it.
I guess that means 'skilled' in a sense. Though I don't think they will have done too many training courses in fruit picking in the manner in which say a plumber, or an electrician has to.
