I stand corrected. I've just dug out my old contract I got from Ryanair when I started and it was issued before I started my type rating. This was under the old system of RYR contract for line training then moved to BRK.
I can't comment on the new deal, but the way they are generally worded is along the lines of "subject to your satisfactory performance during training, you can expect to be employed by us" - no us in the Ryanair contract sense, more us as in you fly our planes.
