They'll likely disappear with the tax break, given that Ireland has since dramatically elevated it's living standard on the basis of low corporate tax (and special tax) and wages are no longer competitive for something like support jobs.

A pretty wide variety of things at this point. So ignore the borderline racist sibling post. And you'll also note they've just announced another 1000 hires despite the ruling.
