The term 'Mark for Misconduct' is a job description that involves assigning a DEMERIT, which is a seven-letter word. A DEMERIT is an official mark of disapproval or censure, usually given as a punishment for misconduct or a violation of rules. It is typically used in educational settings to indicate that a student has done something wrong and should be reprimanded. Demerits can also be assigned in the workplace, where they are often used to indicate that an employee has violated company policies or procedures.
