Bad or unacceptable behaviour by someone in a position of authority or responsibility; bad or dishonest management of duties, especially by a government or military official.
The hospital launched a full investigation after several nurses filed complaints. The senior doctor was accused of serious professional misconduct for ignoring safety procedures. Within weeks, he was suspended and faced a formal hearing that could end his career.
This meaning is about wrong, unethical, or unacceptable behaviour by someone who holds a position of trust or responsibility. Imagine a police officer who is caught taking bribes from criminals instead of protecting the public. An investigation is opened, and the officer faces charges of serious misconduct. This is misconduct — behaving badly when you’re supposed to be acting with integrity. You might hear “the lawyer was found guilty of professional misconduct” or “there were allegations of sexual misconduct in the workplace.” Or picture a teacher who is caught cheating on exam results to make the school look better — that’s a clear case of misconduct that could lead to dismissal. The word carries a strong sense of betraying trust and responsibility. ✏️ Misconduct often appears with words like “professional,” “gross,” “serious,” or “sexual” — each one describes a different type of wrongdoing.
Vivid example: The company’s top manager had been hiding financial losses for months. When the board discovered the misconduct, they called an emergency meeting immediately. He was fired that same week and the case was handed over to investigators.
This meaning is about poorly or dishonestly managing responsibilities that have been entrusted to you, especially in government or military roles. Imagine a city official who is supposed to manage public funds but instead uses the money for personal expenses. An investigation reveals years of financial misconduct and mismanagement. This is misconduct in the sense of failing to handle your duties properly. You might read “the mayor was charged with misconduct in public office” or “the general was accused of misconduct for misusing military resources.” Or think about a government worker who approves contracts for friends and family instead of following proper procedures. The word suggests a serious abuse of the power given to you. ✏️ This meaning is closer to “malfeasance” — it’s not just behaving badly, but specifically mishandling the responsibilities of your role.
Vivid example: The audit revealed that millions of dollars had gone missing from the city budget. The treasurer was charged with misconduct for approving payments to companies that didn’t exist. The scandal made headlines and shook public trust in the entire administration.

✔ Native usage tips
– Misconduct is a formal, serious word — you’ll hear it in news reports, legal proceedings, and workplace HR situations. In everyday speech, people would say “he did something wrong” or “she behaved badly” rather than “misconduct”
– “Gross misconduct” is a specific HR/legal term — it means behaviour so serious that it justifies immediate dismissal without warning. Things like theft, violence, fraud, or coming to work under the influence of drugs are typical examples of gross misconduct
– Different from “misbehaviour” — misconduct implies professional or official wrongdoing by adults in positions of responsibility. Misbehaviour is lighter and often used for children or minor rule-breaking. Don’t use “misconduct” for a child being naughty in class
– Uncountable in most uses — you say “misconduct” not “a misconduct” or “misconducts.” It works like “behaviour” — you can say “an instance of misconduct” or “a case of misconduct” but not “a misconduct”
– “Sexual misconduct” is widely used in news — this term became extremely common during the #MeToo movement. It covers a range of inappropriate sexual behaviour, from harassment to assault, particularly by people in positions of power
– Pronunciation stress — the stress falls on the second syllable: mis-CON-duct (noun). Be careful: the word “conduct” on its own has different stress depending on whether it’s a noun (CON-duct) or verb (con-DUCT), but “misconduct” as a noun always stresses CON
✔ Similar expressions / words
– Wrongdoing → broader term for any illegal or dishonest behaviour; slightly less formal than misconduct; used in both legal and general contexts; “financial wrongdoing” and “professional misconduct” overlap but wrongdoing doesn’t require a professional role
– Malpractice → specifically for professionals (doctors, lawyers) who fail to do their job properly; more about incompetence or negligence than deliberate bad behaviour; “medical malpractice” is the most common use
– Misbehaviour → much lighter and less formal; often used for children or minor rule-breaking; saying someone committed “misbehaviour” sounds far less serious than “misconduct”
