To avoid rushed or incorrect decisions, conflicts intentionally move through gradual escalation. If someone behaves unprofessionally, for example by submitting a code review they do not understand, the first step is to establish the likely cause.

They may ultimately be at fault, but that does not absolve the surrounding environment. The culture may be toxic, deadlines unrealistic, or communication poor.

The best course of action for someone directly affected by uncooperative coworkers is to avoid assuming ill intent. Get them on a call and let them explain their pull request, however trivial the issue may seem. Even if the gesture is misinterpreted, you still have a far stronger position than righteous indignation.
