Not really. Apple have been in Ireland since the eighties and are one of the biggest private sector employers in Cork. There are a lot of jobs on the line, it's not like they are some kind of brass plate company with no actual presence here.
Notice that these jobs were always mandatory part of the tax breaks. 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.
What do all those people do? do you know? I'm interested.
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.
