The term 'Hill Worker' is a broad term that can refer to a variety of occupations related to the government. An ANT, which has three letters, is a small insect that lives in colonies and works together to build complex structures. A SENATOR, which has seven letters, is an elected official who represents a state in the United States Senate. An AIDE, which has four letters, is a person who assists a higher-ranking individual with their duties. All three of these occupations can be considered Hill Workers, as they are all related to the government in some way.
