To answer the original question, Ryanair is a stepping stone airline, they know this, which is why they treat people like ****, in fairness they don't treat their pax much better so what do you expect.
The greatest trick they ever pulled was to convince people that working a stable 5/4 roster flying 800+ hours a year was better than a random one flying 5 das a month you can control through a decent leave/DO system (which by the way Jet2 don't have just yet for fairness in posting but it's the best one I have seen in 3 airlines so far)...
By the way I appreciate the stable roster makes sense for some people's family life so I'm not having a jab the work/life balance of it has just never made sense to me
In short, if I needed a job I would go work for them tomorrow, beats stacking shelves, but if there was any other reasonable flying option I would take that first
