> that isolation allows managers to take emotions out of a situation to make the most rational decisions for the business I know you're playing devil's advocate, but to be on the side of angels: that isolation doesn't promote more rational decisions, only decisions absent a perspective of the company. To the extent that low-level employees don't have valuable information for the business' success, the isolation does promote more rational thinking (where that extent is most often 0). I've never seen a situation where low-level employee wisdom was rightly quashed by boardroom decisions.
