Fraternization

Fraternization, or "to become like brothers," is a term that carries within it the connotation of impropriety. Militaries typically prohibit officers and enlisted ranks from personally associating outside of their professional duties, perhaps to avoid accusations of favoritism, which would challenge military discipline. Private for-profit schools may prohibit fraternization between teachers and students, perhaps to prevent the teachers from contracting with the students for private tutoring or perhaps to avoid potential sexual harassment problems.
