If they did, we wouldn't joke about Congress, the Legislature or conferences on the pitcher's mound. You'd think somebody in management would catch on, but they don't. In fact, they're probably planning a meeting of their own. His minions are summoned, and a series of meetings are scheduled. If things are really bad, an expensive consultant may be flown in to facilitate the situation.
Attendance is mandatory.
All employees show up. But, because they're focused on input, they're ignoring output, and productivity slumps. I have long suspected that many meetings are called because bosses get lonely. Think about it. They have private offices, secretaries to screen calls and underlings to handle complaints.
