GAF15,
mostly STN base offered
If RYR offer STN as a sweetener to direct entrants in preference to their existing pilots, then they shouldn't be surprised to find their staffing crisis goes nuclear when all their current workforce give their notice and move on elsewhere. It's happening already and this would push many, many more over the edge.
The recent DE ads mentioned 'exciting opportunities in Morroco, Poland and Greece'. Fair enough. If they offer the top postings to new boys instead of those with time served, then they'll need extra staff to process all the resignations.
