Romans 12:17–18 gives one of the most practical instructions for workplace conflict: "Recompense to no man evil for evil. Provide things honest in the sight of all men. If it be possible, as much as lieth in you, live peaceably with all men." The qualification "if it be possible, as much as lieth in you" is significant. Paul is not requiring you to achieve peace. He is requiring you to do your part in the effort. The limits of that effort are real and acknowledged. What is in your power to do is clearly delineated from what belongs to God.
Proverbs 22:29 — "Seest thou a man diligent in his business? he shall stand before kings; he shall not stand before mean men" — is a practical observation about the long arc of excellent work. The Hebrew charutz — 'diligent' — means incised, sharp, decisive in effort. The person who does excellent work in a difficult environment is doing something that Scripture describes as having a long arc. The present conflict is not the final environment.
