overthrow of superiors by inferiors; juniors dominating seniors
Refers to a situation where those of lower status or rank overthrow or dominate their superiors. Historically associated with retainers supplanting their lords, but now used more broadly in politics, business, sports, and other hierarchies.
The Warring States period was an era of inferiors overthrowing their superiors.
In that company, a situation of juniors dominating seniors is occurring, with young employees pushing aside the veterans.
