Do not take advantage of a hired man who is poor and needy, whether he is a brother Israelite or an alien living in one of your towns. Pay him his wages each day before sunset, because he is poor and is counting on it. Otherwise he may cry to the LORD against you, and you will be guilty of sin. Policy must be developed with the aim of being fair to everyone concerned. Different incentives can be provided to different people provided that it is clearly laid down before hand what the company policy is for these incentives and that everyone has equal access to the incentives based on their position with the company.
Favouritism is a particular problem in the work place.
My brothers, as believers in our glorious Lord Jesus Christ, don't show favouritism. Favouritism and partiality creates an atmosphere of distrust in the work place. Christians in business must uphold a high standard of equal treatment for all their employees without making distinctions. Those who have believing masters are not to show less respect for them because they are brothers. Instead, they are to serve them even better, because those who benefit from their service are believers and dear to them.
