As a free lance Helicopter pilot specialised in Africa, I am always on rotation, and I change employer all the time.
I wanted to keep paying social charges in France, with the CRPN, whoever the employer.
It seems only Adexpat could do it for me and they now employ me on their offshore company, pay the CRPN contributions and activate / deactivate my employment contract as many times as needed.
This is just brilliant.
