Joe_Bar your question resolves around
the following promise by Ryanair
does it not? So did you read the information at the link I gave in the post above?
What did YOU conclude - beyond the fact that it does not address the
exact situation you describe? (Neither does it address, for example, the current situation of Second Officers who joined on the basis of Ryanair employment and who are now being told that they can only work as contractors - on take it or leave it terms - nor does it address their changed pay conditions, or a number of other issues. But does each and every one of these changes for particular groups have to be spelled out individually ...... or is there not a broader message?).
On one specific question you posed: you should have been able to pick up from a search is the fact that movement to a new Base and a reduction in salary at the time of promotion are "not unknown" (to put it tactfully). Or that the "new 5-4 deal", which will apply to you, allows for a 15% reduction in captain's pay when you get promoted and incorporates a number of clauses which will permit FR to interpret the agreement as they wish.
That's my lot of typing for today. I'm now bowing out of this discussion. Good luck!
