The antonym of "more hard-working" is "less hard-working." It is a term used to describe an individual who is not as committed or dedicated to his or her job or responsibilities. The opposite of being diligent and persevering is being careless and lazy. When someone is less hard-working, it means that he or she is not making an effort to do things efficiently and effectively. The attitude can be due to a lack of motivation or drive, poor time management, or feeling overwhelmed. Therefore, it is essential to push individuals towards positivity, motivation, and dedication to improve their work ethics.
