Tom finds out that his coworker is sharing confidential information with a competitor. what should tom do to handle the situation?
discuss it with his other colleagues so that more people are aware of it
report it to the supervisor
ignore it because it is beyond his scope of work
work out an arrangement that will benefit him monetarily

In this situation the right thing for Tom to do would be to report it to is supervisor. His coworker is sharing confidential information with a competitor which is a violation of company rules and regulations in most places therefore it is up to Tom to report his coworkers behavior. He doesn't need to discuss it with other colleagues and ethically he shouldn't ignore it or try to work out an arrangement that will benefit him monetarily as if he got found out he would get fired.
