I suppose this action from the German pilots has blown a fair bit of wind in the sails of the Irish midget, in so far they've learned that if they can keep any industrial action isolated to a single base at a time, or even a couple of bases perhaps, they can largely cover the holes utilising crew from other bases. And since intended strike action will be declared days in advance, there's plenty of time to position stand-by crew.
What the EEAC have undoubtedly also learned, is that they need to be united over all organised bases in order to make any action felt, and to carry any action out simultaneously across those bases.
EU rules does not allow for sympathy strikes across borders, only domestically; the only way to instigate action across borders, is by coordinating the bases. I'd like to see MoL's face if that happens.
