Colossians 4:1

Masters, give your bondservants what is just and fair, knowing that you have a Master in heaven. 

We all serve someone in some way, whether we are in leadership positions or workers, the bible shows us what is just and fair.  We are called to walk as Jesus walked on this earth and have integrity toward everyone around us.  A world without these guidelines would be chaos.  We must remember that we are accountable not only to ourselves but to God.
