If a person is in a workplace and his boss is doing something unethical what do you do in a worker position ? Do you keep on working for the guy knowing that what he is doing Is wrong ..? Do you confront him ? How do you proceed .?
Saying something to the boss will depend on if he will listen to you or not?
Regarding continuing to work for him, will depend on what exactly he is doing and what your invlovement in that is. I need to know more specifics, in order to answer you.
