The term "rank file" is used to refer to a group of individuals who are at the same level or rank within an organization or institution. Antonyms for "rank file" include hierarchy, pecking order, social class or caste system. These antonyms connote an explicit positioning of individuals based on their social status, authority, or position in relation to others. Unlike the idea of a "rank file," these terms generally suggest a hierarchy of power, with some individuals enjoying more privileges, authority or leverage over others based on their position in the hierarchy. While the term "rank file" suggests an orderly and egalitarian structure within an organization, antonyms for this term imply a more explicit and centralized power structure.
