for the 22 days with NJE, they came around by selling to the authority 22 days + 6 special days off ....some guys don t even request those SDO and if you ask for they will build the roster to get those SDO in your days off !!! in other world you don t get it as holidays, that s a little tricks ..
About the tax in portugal, NI in UK etc....some guys are happy like the dutch or the German cause they will pay a lot of more in they country but the concern of most of the crew is : Once you have paid for all those years taxes and NI outside your country of residence, (on a lower basis for some ), how can you be sure that once retired or in need of your deserved benefits you will get it ?
To whom are you going to claim your benefit.....Dutchland...Germany ..England ???? Netjets says with the form E111 it will be ok....who can certified today that you will get it ? only the Portuguese and the Brits are cover, everybody else is in a grey area!!!
Now lets imagine that it s time to claim your benefits and your country reject your claim because your contribution through England was too little ...you turn toward England and they send you back to your country because you are not uk resident or citizen...what s next ? call netjets HR ? good luck
Its a dream to believe that with only 5.5 to 8 % of salary contribution to NI you will get those great and expensive benefits from continental Europe where others pay up to 45 % to get it...
