British people generally approach conflict with reluctance. If a disagreement can be avoided—if the issue is minor, if other paths exist, if time might resolve it—avoidance is often preferred.
This is not weakness but calculation: conflict is costly, and those costs should not be incurred unnecessarily. When conflict cannot be avoided, the instinct is to contain it rather than let it escalate. Stopping the conflict behavior often takes priority over immediately resolving the underlying issue.
When working with British colleagues, recognize that their reluctance to surface disagreements may reflect genuine preference for working around problems rather than confronting them. “Is this worth fighting over?” is a question they ask seriously, and often answer no.
