What term describes acting poorly in a professional context?

The term that best describes acting poorly in a professional context is misfeasance. Misfeasance refers to the improper performance of a lawful act, meaning that while the action itself is allowed, it is carried out in a negligent or inept manner that causes harm or potential damage. In a work environment, this could involve an employee completing their responsibilities but doing so in a way that is careless or does not meet the expected standards of professionalism, effectively leading to negative consequences.

Understanding this term is crucial because it highlights the importance of not just performing tasks, but doing them correctly and responsibly. It points to the necessity of accountability in professional roles, as even well-meaning actions can result in problems if not executed properly.
