Ryanair is doing what any sensible airline would do in the quieter winter months.
I'm not aware of any other airline
imposing 'unpaid leave' on pilots?
That doesn't mean nobody else is, just that I haven't heard of it.
It certainly doesn't sound like the actions of a 'caring' employer!
After all, I thought this was a company with massive cash reserves???
Sounds like a number of pilots are going to to be using some 'cash reserves', in order to excuse MOL from using his!
