if a strike happens in March (no way will the government allow it) over that weekend.
I assume you mean that the Government will not allow a strike to take place over the St. Patrick's weekend (because, of course, they're all lined up for their annual worldwide junkets partly, at least, on Aer Lingus flights) and, if so, what action do you think they (the Government) are likely to take that will stop it. A lot of people are on tenterhooks over this as the DAA is also involved as far as we know.
