If you really....really....want info on this, then pick up the phone to Baldonnel, 01 403 7514, the folks there will be most helpfull.
Bare in mind though, that almost all the qualified ATCOs there applied to get OUT, when rumours of jobs at Dublin surfaced. Unfortunately, they were just rumours, at least for military ATCOs...(and ex military..
)
Best of luck, you'll need it.
