the plus side of that is if you move from Dublin to the country, you keep your salary the same but everything else is cheaper (well, houses etc.).
The private sector get shafted if they leave Dublin as the wages drop dramatically, but the benefits of not being there make up for it
Edit: Actually, considering the unionised state of nurses pay, does that mean that staff outside Dublin 'already' get pay on a par with their colleagues in Dublin, where things are more expensive ? Is there any benefit to being a nurse in Dublin ? Is there any drawback to being a nurse outside Dublin ?
