I need help please. I have seen ethical behavior in business largely being driven by the behavior of colleagues or co-workers.

For my discussion I am trying to provide journal evidence and justification for this claim (peers help shape ethics). I am trying my best to build a relevance section as if I was going a research paper. Trying to find an article that relates to ethics and the influence of peers in ethics. I am reading from my business ethics books and multiple journals. Thank you very much.
