Surprised ? . . . . thought not.
I guess as they are only on unpaid leave not unemployed they can't claim any unemployment benefit, and , as has been said before ,are not "allowed" to work for someone else as they are still employed by Ryanair, although for the ones who are contractors I doubt that would stick.
For the new F/O's struggling to pay off their training debts this is going to be a very tough time, many will also have less than 500 hrs on type which makes them less attractive to potential contract agencies. Hang in there guys there is always Macdonalds. . . again.
