French culture expects that reason and argument should govern conflict. When disagreements arise, positions should be articulated clearly and defended with reasons. Challenges should engage substantively with opposing views. Resolution should emerge through intellectual process rather than through force, authority, or mere assertion of preference.
This means French colleagues expect you to explain why you hold your position, not just that you hold it. They will challenge your reasoning and expect you to respond to their challenges substantively. Those who can articulate reasons have advantage; those who merely assert preferences without supporting argument find their positions carry less weight. French education trains people in structured argumentation, and this training carries into professional conflict.
If you engage conflicts with clear reasoning, substantive responses to challenges, and willingness to modify positions when confronted with superior arguments, you will earn respect. If you rely on authority or preference without supporting reasons, you may be seen as unable or unwilling to engage properly.
