Let’s run it up the flagpole and see who salutes

“Let’s run it up the flagpole and see who salutes” is an idiom that means to propose an idea or suggestion to see how people react to it or if they show support for it. It’s often used in a business or professional context to gauge the response or reception of a new concept or plan. The Idiom draws its inspiration from the practice of raising a flag on a flagpole to signal something important or to gather attention. In this case, “running it up the flagpole” refers to presenting an idea or proposal to a group of people, like raising a flag for everyone to see.
The phrase "see who salutes" adds an extra layer to the idiom. Saluting is a gesture of respect or acknowledgement, typically used in military or formal settings. So, when we say “see who salutes,” we mean observing who shows support or approval for the idea or proposal. Essentially, this idiom suggests testing the waters and seeking feedback or reactions from others before fully implementing or pursuing an idea. It allows for gathering insights, opinions, and potential challenges or concerns that may arise.
