GUSTO - you management types make me laugh! Could you please refrain from masquerading here on pprune as anything other than the moronic GlobalJet Manager you so obviously are...
The French are infamous for nepotistic promotion and favouritism to their own. If what you say is true about it being a French Company with French Managers, then for a non-French national, it would be a great place to stay away from !
Of course, should Luxembourg elect to expel you, you need not worry about finding another non-French country to base your French company in. The UK would love to have you, along with all the other gazillion nationalities that fly for UK based operations.
