Conflict handled well is maintenance, not damage. Teams that never argue are usually just pretending.

Disagreement in a working group is a sign that people care enough to hold positions. Teams with no friction are usually not harmonious, just quiet, and the disagreements are happening somewhere you cannot see them. Handled openly, an argument is how a group adjusts to new information. Avoided, it turns into a distance nobody can point at.

When something bothers you this week, raise it while it is still small and about one thing. Say it to the person rather than around them. Aim to leave the conversation with a decision rather than with a winner.
