Ethical social work practice within criminal justice settings is fraught with challenges. Through individual interviews in a qualitative study exploring social work practice in diverse criminal justice settings in the northwestern United States, a subsample of 9 social workers described the difficulties they experience adhering to social work's professional code of ethics. They identify 2 primary areas of divergence, conflicting responsibilities and opposing interests, and identify the ways they respond to these challenges and the rationale behind their decisions. The discussion section explores avenues for strengthening social workers' abilities to be a vital and ethical presence in criminal justice settings.
