Just couple of questions Andrew 7, is the agency paying CRPN, a mandatory French pension for aircrew, on behalf of your nephew?
Does your nephew know that take home pay in France is before income tax and that the taxbill will follow next year?
Does he know that the contract has to be according French labor law?
Is he respecting flight duty times as stipulated in the "code de l'air"?
If the answer to one of the above is no, his brilliant time may and probably will end in court one day. Ryanair. EasyJet, Vueling, City Jet and even Air France as well as some of their pilots have been convicted in the recent past.
