Hierarchy
In France both business and political life are characterised by a strong hierarchical structure in large companies. Positions and the corresponding power are clearly defined. And when dealing with the French, you should stick to formal etiquette.
Respect for authority in French organisations is based on respect for competence. The PDG (Président Directeur Général) or ‘patron’ (general manager) will be expected to possess a strong authority and general expertise. Usually, the patron does not have any personal relationship with subordinates in or outside of the office. He/she is shielded by his/her secretary. Hence, if you try to contact people at top positions you always have to get past their secretary first
