Thats the way it should have been done with the BRK contracts also I assume if it was done right..
The Hourly Block Rate paid by Ryanair to make that worthwhile would have to be so high that they may as well just employ you directly to begin with!.
But as I suspect a lot of people look at the top line and then hope to get a "Good Deal" with there accountants magic wand to keep more than they should..
It won't happen but people should vote with there feet and not accept this type of professional employment
All just my own humble opinion of course.
