Mik3bravo you’ve obviously never dealt with Ryanair management then or been an employee. It’s very easy to say what should happen but you’re not dealing with a rational employer. The sheer numbers involved (pilots and cabin crew) at present in the majority of jurisdictions should be giving you an idea of the scale of the issues.
Unfortunately any strike in deepest darkest winter would be futile and the company would easily cover the lines of flying affected. Sometimes the only way is strike action in peak season; yes the consequences could be reduced bookings but let’s not assume that would be a bad thing as it could lead to whole scale change within the airline and a better employer in the future.
