●the tail (is) wagging the ˈdog ( let the tail wag the ˈdog) used to describe a situation where a small, unimportant thing controls a larger, more important thing本末倒置；喧宾夺主◆In this company the workers tell the manager what he can and cannot do. It’s a real case of the tail wagging the dog.这家公司里是雇员规定经理的职权范围，真是上下颠倒。
