Here you can find your answer to your "floating base" concept, it comes from those idiots in Brusselles:
the concept of “home base” for flight crew and cabin crew members is defined as the location nominated by the operator to the crew member from where the crew member normally starts and ends a duty period, or a series of duty periods, and where, under normal conditions, the operator is not responsible for the accommodation of the crew member concerned. In order to facilitate the application of Title II of this Regulation for flight crew and cabin crew members, it is justified to use the concept of “home base” as the criterion for determining the applicable legislation for flight crew and cabin crew members. However, the applicable legislation for flight crew and cabin crew members should remain stable and the home base principle should not result in frequent changes of applicable legislation due to the industry’s work patterns or seasonal demands
By the way, dear A&C, you talk about crews like if they were objects that can be moved around without any mutual agreement, sent to this base or another without asking their opinion....a perfect ryanair boy.
There are countries where workers must be treated like humans by law, unlike Ireland.....
