Sometimes we are confronted with unethical practices of our employer or manager. So what should we do? 
Let’s begin by saying that if the product or service your organization is engaged in is not contributing to the good of society, you need to question seriously if God wants you in that company. For example, being employed by the lottery commission or a beer company would place you in the position of promoting a product that brings destruction and grief into our society. 
I can’t believe that Jesus would want us to expend our time and gain our financial support from such kinds of goods or services. They may not be illegal, but certainly they are not edifying or positive forces in our communities.
Suppose, however, that you work for a firm that is providing a good service, but you are aware of unethical practices that are allowed or encouraged. Maybe hours are billed to the client which were not actually worked and expenses are charged which were not incurred. As a Christian, what action should you take?
Well, using that example, if you were asked to exaggerate the hours or expenses, I think your response is clear cut. As Christians we should never be part of lying or dishonesty of any kind. We have to draw clear black and white lines in our behavior in situations like this. God does, and He requires the same of us.
Of course, when we take these difficult stands, we must always try to do it with as little fanfare as possible and as gently as we can. If you don’t have to say anything at all, that is best. Just do what is right and let it go. But if you’re told to do something unethical, or asked why you didn’t, that’s when you must be willing to say that you have done what you believe is right and accurate and you’re not willing to do anything less.
A friend of mine lost his job once because he refused to falsify a government report for his employer. He was unemployed for a few months, and it looked dim. But the Lord has blessed him, and now he has a much better job in a firm that is very ethical.
Ethics in business have plummeted to very low levels, and if someone’s not willing to stand against it, it will never stop. As someone has said: All that it takes for evil to succeed is for good people to do nothing.
