Hard workers are individuals who put in a lot of effort and dedication to their job. Ants, TOILERS, SERFS, and ROBOTS are all examples of hard workers. Ants are small insects that work together to build complex structures and collect food for their colony. TOILERS are people who labor hard and long hours to complete a task. SERFS were peasants in the Middle Ages who worked on the land of a lord or noble. ROBOTS are machines programmed to perform specific tasks with precision and accuracy. All of these hard workers demonstrate the importance of hard work and dedication.
