Sense: noun/1

'Top brass' is an informal collective noun for the most senior decision-makers in an organisation, originally from British military slang where officers wore brass rank insignia. 'Management' is broader and more formal — it covers the entire administrative layer, not just the top tier. 'Leadership' is even wider, referring to the quality or activity of guiding others as well as the people who do it. 'Higher-ups' is similarly informal but leans on hierarchy rather than authority; it can sound dismissive. 'The brass' drops the 'top' and is the most colloquial — you would not use it in a business presentation. Example: 'The top brass approved the budget, but middle management had to implement it.' Compare: 'The higher-ups never listen' sounds like resentment, whereas 'The leadership made a wise decision' sounds respectful.

Etymology

The phrase comes from British military slang of the 19th century. 'Brass' referred to the brass or gold insignia — badges, buttons, and stars — worn on the uniforms of senior officers. These visible markers of rank made 'brass' a natural metonym for the high-ranking officers themselves. By the early 20th century the expression spread from the armed forces to business and government, keeping its informal, slightly irreverent tone. The 'top' was added to distinguish the highest tier from officers in general.
