B738driver,
Point 2 you described has already been pursued by a few FR employees and guess what? Didn't work.
Point 1 has been pursued by some but as far as I know there has been no support whatsoever from the company.
The focal point is about the concept of permanent establishment which activates or not the DTA; according to the Italians Ryanair has a permanent establishment in Italy therefore italian laws should have applied both tax and social security wise.
Lots of speculation in this thread and lots of personal opinions but so far there are a few facts which are quite serious and those are tax prosecutions for Ryanair employees and an upcoming court cases for unpaid social security.
But the most serious issue is the fact that the are pilots flying around under these kind of un-acceptable psychological pressures who are being left completely alone by the company that has put them into this kind of trouble.
