A hot-tempered man stirs up strife, but he who is slow to anger quiets contention. - Proverbs 15:18
"Be subject to rulers and authorities, to be obedient, to be ready to do whatever is good, to slander no one, to be peaceable and considerate, and always to be gentle toward everyone." - Titus 3:1-2
Be a light to your workplace. (But if that's a struggle right now, just do your best not to be the source of drama.)
Don't fight the person God is trying to make peace with.
